Balanced wd is pretty decent at mp7/8 range, 1.2 aps weapon, -bears cost on all possible slots, and you don't use any other damage skills.
But to be objective here, cm wizard is better. Ask youself again, what is better than cm wizard? You have ability to perma stun elitepack, very high damage multiplier on top. Constancy that comes from perma stunning makes most difference. What is biggest problem of all builds (especially bear wd) on higher mp? Ranged elites that run away. Every class except wizard is losing dps vs it. If ranged annoying AI elites start running each in opposite direction, on high enough mp that you can't burst them down in 3s, you lose a lot of time there. Even godly barbs, chase occultists down with hota, one by one. Try to hit them with cluster bomb or spike traps as dh. Bears are probably hardest spell to aim vs enemies like that.
Wizard basically grabs entire pack from first second of a fight, and they cannot move from that point, getting full dps in the face, whole elitepack is being damaged equally, all rare affixes they had are cancelled by perma stun mechanics of cm wizard. That makes wizard not only better than wd for highest mp, but imo better than any other class, because there is just no affix combo on elites that can increase duration of fight, it is all about their hp, nothing is random.
Think of it this way, if blizzard introduced MP11, hp x10, damage x10, monster speed x10. Wizards who hit perma stun breakpoint could farm something like that easily.. while other classes would stand no chance, no matter that build they use. This is how broken perma stun is.
