not really, considering he barely beat with his 700k sheet dps 2 players who had at best 400k sheet dps fully buffed so unless he does it with a different spec i think a barb or DH with matching gear could easily beat him (no offense to him, its just the way the game is designed)
Wizards skills inflate the character sheet dps more than any other class can do (GC/force weapon/sparkflint/pinpoint). Those players have, in fact, nearly matching gear. Diabloprogress is far better at comparing gear than bnet profiles.
Probably won't see a WD reach that DPS because of mana cost restrictions. All the super high DPS WD's have insane AS, which means bears go for about 3s then OOM. They can use sacrifice on dogs to get back to full twice in a fight, then done... so about 9-10s worth of bears DPS. That just won't cut it. None of our gear has things like "mana on crit" or some such like all other characters have.
The best we can do is a no mana build (like mine; Insect#1546) and just go for it. Fastest would be a 90-120s I'm guessing.
Probably not, because Archon would only last part of the fight, unless maybe he ran in there with a super charged Archon timer from clearing lots of mobs before hand. Even then, Archon is 3.75 times listed dps while the CM spec can go over 4x listed dps, so it's actually higher dps with the right gear.
