Barb - sprint tornadoes
Monk - Nirvana (look it up)
Wizz - CM
WD - incredible passives like Grave injustice and mana regen scales very well with gear
ok.. to be fair we have Marked for death (mortal enemy) and bat.. but mortal enemy only works on 1 monster wich usually dies quick unless it's an elite but still... even If you have max hatred regen possible on gear you still can't spam your hatred skills effectively like other classes can.
I understand it is dangerous to increase hatred regen because of the risk that hatred generators become obsolete but I feel that because of that our spenders should do a LOT more dmg, since we can't make our hatred 100%uptime like other classes. Almost everyone uses spike trap (Eb) because its the only skill that for 30 hatred can hit 3x 275%, wich is the best dmg per hatred spent..
Please blizzard give us some feedback, we really want to hear your opinion on this !
edit: corrected EB dmg said 375% its 275%
