There have been a good number of posts on the topic of AA specs, and even more pertaining to AA specs after you get your mythical. (I'm assuming DPS spec.) Instead of just posting a pic of my AA's, I'm going to break them down into 2 categories, AA's any dps conjuror MUST have, and ones that arent necessarily vital, but can come in handy for different reasons.
CONJUROR TREE
MUST HAVES, Regardless of mythical (And why)
Evocations line should be maxed. This means 5 points into every single spell, including solidify and frigid winds. These are our primary dps spells, to not put all the points in them is to decrease our dps. There have been arguments that it is counter-intuitive to shorten a snare, HOWEVER, given that we are a DPS class, who cares how long the snare works. Shorter = more dps. You should also have Unabate. 20% reduction in resistability for your and your pet means you land more spells meaning greater dps.
Enhance Blazing Manifestations: 2 AA's (6 points). Given that the 2 AA's mean 2 more triggers of Blazing (to the tune of about 1.3k damage) this should be self-explanatory. Properly used, BM can account for a good chunk of DPS.
Enhance Elemental Unity: 5 AA's. 5 more seconds means another good 3-5 more procs of Elemental Vestment. Seeing that EV hits the encounter for 600 (I think, at work, cant check), this should be self explanatory as well.
MUST HAVES, without mythical
If you don't have your mythical, even if your mage pet is M1'd it has 1.5ish hp. This means it is going to die to AE's a lot unless you do something about it. If it dies, you either go a fight w/o your pet, meaning loss of good dps, or you recast it for 10ish seconds, meaning loss of dps. So its helpful if it doesnt die.
There are essentially 2 ways to prevent your pets untimely demise, either spec for bubble, or spec for max Foundations line. IMHO, I prefer the Foundations line, but either can work.
BUBBLE APPROACH
If you choose to spec for Bubble, you may as well gain some dps from it. If you have the points into Blazing Manifestation and Elemental Unity (Like you should) you only need 9 more points in Abjurations to get yourself Bubble. I personally, would recommend putting 4 points into Geoticism, 5 into Infernoshield. You could also however put 4 into Geoticism, and put 5 into Magma Seed (You have 5 points into Solidify right....). Grab Bubble and your set.
FOUNDATIONS APPROACH
This is my preferred method of pet protection, however, it requires a bit more paying attention than Bubble. If you choose to use this you should have 3 points into heal, and max points into everything else (Vehement Gem, Master's Intervention, and Enhance Stoneskin). You can also grab the Elemental Cure to give yourself a nice simple way to get down to Blazing Manifestation and Elemental Unity. You will also have enough points to get the Group Stoneskin which can come in pretty handy at times. It does protect your pet after all.
BUBBLE VS FOUNDATIONS
Bubble works great, as long as your pet is NOT attacking and is near you. This means that your backing your pet off for every AE call, and possibly having to Call it back to you. Depending on how far out your having to joust, you may or may not be able to lay down damage from where you are. If you are in range, that is time wasted that you could be DPSing. if your out of range, though you cant do any Direct hits, you could be casting Blazing Manifestation or Elemental Unity if theyre up. Bubble, however, is much less work intensive and is much harder to mess up than the foundations line.
The foundations line is nice because casting any one of the pet protects is very rapid (outside of group stoneskin if you got that). This means that on an AE call, YOU joust out and DEPENDING on the AE, hit either Vehement Gem, or Minions Intervention (Pay attention to WHERE your pet is. These spells have a limited range. If you can avoid call servant you want to.) . If the AE is physical based, you want Gem up, if its a spell, you want Intervention up. This requires you to know WHICH one is coming and to hit the appropriate button. Another options is to hit your stoneskin, which now protects your pet, and use that. The reuse is a bit long on that to be able to do it every AE, but can save you if your unsure on one. The advantage to this method is that your pet never stops casting (And given that your using youre mage pet, right? means that your pet wont have to get going again once the AE hits. Mage pets can take a good 2 seconds to get casting again) it also allows you to still remain casting as well, seeing that you dont need to use call servant. (If in range, continue as normal, if out, try to cast Blazing Manifestation or Elemental Unity.)
If you arent sure which to use, choose bubble. A non-casting you/pet for a couple seconds is much better than a dead pet and needing to resummon one.
IF YOU HAVE YOUR MYTHICAL
The mythical pet has a solid 7.5k hp. It can actually take a decent AE hit w/o eating dirt, meaning we dont have to pay quite as close attention to it. It also means we don't need to have quite so many points into protecting our pets, meaning we can spend them other places. This doesn't mean you shouldn't put any points into pet protection, it just means you dont necessarily need to put quite so many.
FOUNDATIONS REDUCTION
If you were foundations spec'd, you can ditch most of the points in there. I personally got rid of everything except pet heal, and my points into enhance stoneskin. The points in the heal let me get to Cure Elemental and down to Blazing Manifestation and Elemental Unity.
BUBBLE REDUCTION
If you had points in the line you didn't want (besides bubble itself), get rid of them. Chances are, you dont have to many out of here you want to thin out. If you still have enough points for Bubble, you may as well leave it. Hell, whats one point. If not, well, its a point you have for elsewhere.
WHERE TO SPEND THE REMAINING POINTS
If you have your mythical you have a few extra points than if you don't but the philosophy is the same.
Infernoshield: Points here mean more damage everytime your tank gets hit.
Magma Seed: Though its not as powerful as may would like, dps is dps. If theres no where else you want to put the points, go for here.
Enhance Fire Pet: Less resists means more dps. Even if your pet doesnt get resisted often, it can't hurt.
Enhance Swarm Pets: Faster casting.. Should make sense by now.
Enhance Plane Shift: Arguably our most powerful spell, 20% to all the attributes is a nice addition.
Pet Heal -> Enhance Stoneskin. This gives us the option to Stoneskin us (and our pet) and then Expire the pet. The stoneskin takes the hit, and we still heal the group for 2k. Not much, but can be the difference between a group wipe, and the healer catching up.
SUMMONER TREE
Thankfully, the summoner tree is much simpler, and it doesnt change once you get your mythical.
MUST HAVES
Intelligence Line: The critical ones are the last one, Arcane Minion, and the final point, Empower Servant. You should have 8 in Arcane Minion, which means you have 4-4-4-8 and you need to spend 2 more points to get the final one. Where you choose to spend them isn't terribly important.
Strength Line: The critical one you need is the last one, Wild Channeling. That amount of crit chance is nothing to laugh at. It should be 4-4-4-8.
Wisdom Line: The critical one you need here is.. Yup you guessed it... the last one. 4-4-4-8 again.
WHERE TO SPEND THE REMAINING POINTS
At this point, you've likely spent 64 points, and you have 6 to go. Here are some places you can spend them.
Magician's Intelligence: More intelligence is never a bad thing, but given the amount you can currently get from gear and buffs, its by no means crucial.
Minion's Warding: Generally, a chance for you taking no spell damage is a good thing. Note: For those with Bloodthirsty Chokers, this means a chance to reduce/absorb that damage as well, so investing points here is a good idea. (Thanks Terra)
Minion's Barrier: Increased pet defense means that an AE physical attack (Quite common in RoK) may not be lethal.
Animist's Transference: Single Target heal, handy, but given that we are a dps class, kind of pointless. Healing should be done by... healers.
Theurgists Strength: More strength means more stuff you can carry, and a slightly harder melee hit if you melee... like you should.
Perceptor's Stamina: More Stamina means more hp, means less of you dying.. Generally considered a good thing, though i know of a few exceptions 
If anyone has any suggestions for changes, let me know. Ill make changes as I see fit. Hope this helps.
