http://us.battle.net/d3/en/profile/Hellocopter-1952/hero/29505154here's my zombie bear build, it's got -22 bear and 90 mana regen 1.56 attack speed,
i find that 1.4-1.6 is a good attack speed for zombie bear stutter step (move, bear, move, bear)
i tried going slower but the cast speed turns it into more of a stop step (move, stop and wait for bear, move, stop and wait for bear), really annoying and slow for speed runs.
i can cast 18 times before running out of mana with blood ritual (and not using spirit walk's mana regen), which if u manage correctly can dish out ~25m in dmg before running out
it's pretty expensive since my items are pretty much the best as i can get them with the exception of boots and inna's pants, i've found better ones with +20 more stats, but the cost isn't really worth the upgrade, also been using all my demonic essences on new bracers, but looking for int, vit, ar, armor, crit and pickup is near impossible
