Well, I now have two hotbars, one for Spells by damage potency and another for spells by Overall Time Efficiency.

Timed results show with one mob or multiple mobs, extra boe, or group procs, etc that for fights that last 1-20 seconds, casting off spells by their Damage Potency is the way to go, but for longer fights of 20+ seconds OveralTimeEfficiency develops a higher average of dps.

Just to let you know you made the most basic mistake that every other person who tries to make a spell effeciency/potency/burstdps chart does. You left out the recovery time that occurs when you cast a spell. Granted all spells have the .5 second recovery time, but this added time will alter your calculations on best spell to cast if there is no other concern.

Basically what I am saying is that a spell that does 1,000 damage and takes 1 second to cast compared to a spell that does 3000 damage and takes 3 seconds to cast. with your basic math both spells will appear equal, however the 3,000 3 second spell is the better spell to cast due to the damage to toal time spent in casting aka 3.5 seconds.

So basic math:

spell 1 1,000/(1sec casting + .5 sec recovery) -> 1,000/1.5=667 dps
spell 2 3,000/(3 sec casting + .5 sec recovery) -> 3,000/3.5=857 dps

As you can see the recovery time impacts the faster casting spells more so than the slow casting spells.

Also BoE or +spell damage is already figured into your spell discription.

Boggles the mind how many people forget about recovery time.

Ok, I recall reading about that, but wasn't sure because I don't ever really feel like I have a .05 sec delay in casting.

But for the formula I'm mainly choosing, OTE it doesn't make any diff for the weight of the spells or the casting order for single mob, multiple mobs, w/or w/out procs.

Just added in the .05 seconds, ran all the test, and everything shifted equally.

So thanks.... It will impact the dmg potency bar.

Just to recap for me I'm showing if I just use dd/dots that if the fight lasts longer then 25 seconds I should use OTE, if it's before especially before 20 seconds, then the Damage Potency is the way to go.

Couple of things:

Average damage should include a spell crit%. I can give you a formula for this tomorrow (4am here!) if you don't already know it!

Also spell potency vs. "overallspellefficiency":

Surely spell potency is the best thing to use here. This gives you a nice ranking of which spell is going to do the most damage per second (as you've used total damage/casting time). The only exception would be FA as pointed out before which can be recasted before all the damage has occurred.

So lets assume you recalculated FA using total damage as (initial dmg + tickdmg*recast in ticks). You then have a listing of which spells are doing the most damage for their cast time.

In other words, you cast those spells as soon as they are up for max dps. **

You then go on to calculate overallspellefficiency, which basically includes the reuse timers. As far as I can see, this just tells you which spells are going to be the overall most damaging during the fight, the data for which you could just get from a parse ;) - I don't really understand how you can use recast to form a list to say "use these spells as soon as they are up, in this priority".

Let's put a garbled post into some numbers.

spell 1 : 10 damage spell for 2 second cast, 3 sec recast = 5dps (aka damage potency)
spell 2 : 50 damage spell with 4 second cast, 5 sec recast = 8dps

makes sense you'd cast 2nd spell whenever you can
1: overallspellefficiency = 5/3 = 1.66
2: = 1.6

Spell 2, despite being better dps, scores lower because it is not up so frequently. So forgive me if I'm wrong, but preferably casting spells with a better overallspellefficiency would lower your dps.

Actually registered just to say this post is great, thanks for taking the time to work it out and sharing it.

Sticky might be a good idea?

So...
Am I the only one that lags so much that the recovery time really doesn't matter?

Simonsays

I don't normally lag, but i use a low setting since I run 2 accounts on 1 computer.

I lag so badly most of the time that the only thing that saves my dps is the queue option.

Go go casting 3 spells before the screen moves!

This guy did show the formulas well, but failed to see two things.

1) You should choose the spell with the less casting time due to procs (gear/group/etc)

2) In a raid you should wait for all the spells with the lowest recast time to be used before casting those with higher recast times, so you never fail to have some spell to cast.
