- Berserker
Revenge have 35% chance to deal extra dmg x7 or instantly kill non boss target, instant killing doesnt work on elite mobs.
This talent can be replaced with talent which allows berserker hit additional target with 2 handed weapon. I wasnt in situation where i can use this talent, because aoe from autoattack work only when addtional target stay very close to main target. Remove additional dmg from berserker's rage will be better in any situation. Also berserker can kill most mobs pack with Q-R-D combo.
- Crusader
Guardian angel also protect target from any source of dmg and redirect it to crusader.
This talent can be replaced with talent which decrease cooldown on hateful strike, gaping wounds and revenge, this talent a little useless, because on 50 lvl you can pick more useful talent which reset all cooldowns when crusader autoattacking enemies.
- Hunter
Each point of agility add 0.25(or 0.5)% of attack speed.
This talent can be replaced with talent which give immune to critical hit for pet, it's one of most useless talent because hunter always overaggro his pet and pet never get hits from bossesm, i've never seen players who take this talent, also most of spells doesnt affect on pet.
I hope you understand my bad english.
