the new taunt logic only use when you need it.
It doesn't taunt on mob that:
- Targeting another tank
- Targeting a pet (i prefer let pet die so warlock/hunter need to learn to set pet taunt off)
- Mob targeting your friend but your friend threat level < your threat level. This is a new addition because a lot of mob targeting another player to cast a spell not you event you are firmly holding aggro. After casting a spell, mob will target you back so there's no need to taunt in that case.
