Good info there Zwi.
I know Hydra is what everyone is looking at for the moment, but I was thinking something like this.

A Wand of Woh build should also be strong. I intend to hit the 54%+ CDR with my team to take advantage of perma freeze lock with cold snap. Since I am playing close Explosive Blast pairs well as a main damage source and it takes advantage of Audacity passive.
Here is a little breakdown.
Mammoth Hydra = 330%/sec x2 (SS) x 7 (Tals buff) * 2 (FnR buff not accurate because it is actually higher at 125% but good enough for camparison) x 2.5 (the number of ticks/sec at the 3.08 APS breakpoint for hydra... this needs 50% TnT and 38% character ias to reach with a SS with 7% ias on it)
Mam Hydra DPS = 23,100%/sec
Doing the same calculation for Explosive Blast yields:
520% x 3 (the number of hits of concussive rune) x 4 (total casts with Woh) x 7 (Tals bonus) x 2 (FnR bonus) = 87,360/cast
Now divide it by 2.6 (cooldown of EB is 2.51 at 58.18% CDR which this build can hit with perfect rolls) and you get 33,600%/sec
EB seems to do more damage than Hydra. Both Hydra and EB can take full advantage of Arcane Dynamo so they are both equal in that regard. EB has the advantage of being able to keep up Taeguk much easier than the SS Hydra build though and the EB build has no reliance on IAS so gearing allows for higher CDR, CHC and CHD. Both builds can access the same amount of +skill damage for their main skill.
The Woh build can use EB at 25% effectiveness compared to EB and the EB build can use Hydra at 25% effectiveness of the Woh build. So they are equal in that regard. (EB build Hydra will only hit 1.25 ticks/sec breakpoint since it doesn't stack IAS and only has one hydra so that is how I calculate 25% effectiveness... in truth it is higher since the EB build can stack CHD and CHC much easier than the Hydra build do to not needing IAS on gear.)
Whichever build you choose one of your characters can use EE to give the entire group 20% damage. I don't like Strongarms because they are only useful for trash and elites that can actually be pulled. APD's should provide an enormous amount of toughness so I focused my passives on DPS. Force Armor could be swapped to something else if needed.
The only thing my build doesn't really have is a pull mechanic. Right now I was using Arcane Orbit since it can be cast off the gcd making EB and Orbit two easy to maintain buff abilities for the Talk 6p. I could easily swap it to Black Hole for a pull since BH would have just over a 5 sec cooldown on this build at perfect CDR. In that case, I would probably use either the one that clears ground effects or the one that buffs spell damage based on number of mobs hit.
I feel the Woh build might perform better than the Hydra build for multiboxing. Simply because it would be easier to play and the gearing allows for easier time getting CDR while still keeping other dps stats high. The Hydra build is far better for soloing where you can't rely on perma freeze and being in close proximity to mobs as well as for grouping when you are only playing a single character. In group situations because of Tiki Doc and Crusader controlling mobs and providing BBV and other attack speed buffs the Hydra build can reach the 4.03 and maybe even the 5.8 breakpoints with enough mobs nearby and pain enhancer. When reaching those breakpoints the Hydras will outstrip EB. Normally you would only be able to hit the 2.5 ticks/sec bp with decent gearing, but with group IAS buffs from an ideal party if you hit the higher breakpoints the next one is 3.33 ticks/sec and the highest one is 5 ticks/sec. The damage really ramps up in that situation.
Getting good Woh's and SS's on 4 Wizard's will be no easy task though. So I plan to work out a build I can use without a specific weapon. Unfortunately Wizard skills are kinda bleh without weapon support so I am not sure where to start on that heh.
