Time for some bored at work ramblings...
Mindwarped numbers seem a bit high, but that is coming from someone with a heavily stacked group.
I don't often run with my choker as it can get a little hairy at times and messes with my furies casting order and dps. Since he often parses 3k-3.5k in VP while pure dpsing I usually leave the choker in my packs.
Atm I have 85 crit and 650ish +spell w/ Mayong Orb, no 3 set bonus, and back to no Mythical (

hopefully we finish up this week).
Most of this expansion I have been without a Wizard also (pretty much just a troub).
In VP I am typically 10%+ of the raids DPS. When there is a fair amount of lag I parse in 3800ish range w/ troub and gear listed above. Lag free I can push 4500 peaks rarely 5k. How well I do depends (especially ZW's) on how much of my focus is dealing with officers, sending gay cybers, and generally being an ass or fucking with people in vent.
Lag free and not slacking I see Calaglin's numbers as pretty accurate with gear fleshed out, mythicals for self(pet)/raid, and semi-generous group setup. Those numbers will not be easy though. I only expect the top Illusionists (in fairly high DPS guilds) to be able to pull those off consistently.
With our wizard, 3 set bonus, my mythical (pet), lag free, 2 PotM's, a few more pieces of gear, and a relative increase in my raids dps, I expect some HUGE increases in my DPS. It's gonna be fuckin sweet!
I always recast pessimism before the duration is expired, and rarely let brainclot terminate. I probably should test this more, but with 2 PoTM, VG, Aria, Tandem, some proc gear, and decent BoE, I imagine brainclot on average will do more by recasting when it's up. A combination would probably be the best.
Hmmm... how bout setting up an ACT ding for when PotM/VG starts/ends? I assume they both have emotes that can be used? I usually do a slight modification of my casting order when I know they are up. This could be useful in squeezing out some extra DPS.
I'm gonna go a bit against the grain and comment on damage proc gear. In short, I think most damage proc gear is over-rated. Anytime someone suggests a replacement they get flamed.
Personally, if I think 2 items are fairly close in the DPS they generate, I choose survivability (hp/sta and to a point, resists).
My BCG replacement is Death Bringer's Cord, and instead of Invoker I use Crystal Gift/Remorseless Hoop/Thuuga Earring.
In my standard gear I use 1 damage proc item, Praetor's Guard. I then keep BCG, Invoker, and BoT bagged for AE fights. The most controversial of my choices would be BCG and Invoker. With high crits I can see the value and power of these 2 items, but I'm sorry folks, I just don't agree they are the end all.
#1 Streaky as hell. I have seen numerous ZW's where they end up with 20-30dps. Not good enough. The +spell/crit from replacements is consistent dps, although the crit values are a bit less against high con mobs.
#2 Shitty stats. While stats overall are somewhat worthless, the replacement items have high HP, Sta, Int, Power, Resists, +skill. Individually not that important, but just the HP/Sta alone can sometimes translate to less death and alot more DPS because of it.
#3 At best there is not a huge difference in the dps the items provide. There are certainly times where the proc items hit a rng streak and go insane, but otherwise, the difference is not great enough so I'll stick with only swapping them in for AE fights or maybe when the proc increaser clicky is up.
Trak belt will certainly replace BCG though.
Something else... Our raid has 3 Illusionists. I have not really tested it yet, but how do multiple Tandems stack? A.) Only 1 works. B.) They can both trigger off 1 cast. C.) Having 2 increases the chance to get a proc on 1 spell, but it procs max of 1 per spell cast.
Alright, done rambling for now. Back to what I call work.
