Is there a list of interrupts by class? Looking through the forums, there seems to be very little information.
Rogue:
shadow pris, vanish->sneak attack
Mage:
Silence(general), discharge
Warrior:
Thunder, surprise attack, shout, blasting cyclone
Knight:
Charge, shock
Warden:
Soto->entangle(not reliable)
Druid:
Binding silence
Champ:
Electrocution(general), shock strike(general), rune draw, vacuum wave
Warlock:
Soul trauma
Scout:
Throat attack(general), neck strike
Priest gets nothing outside elites afaik
I've probably missed a few and didn't include any elites because I'd rather not look them up also didn't include cc skills like numbing dagger or static charge that accomplish the same thing but might not work on a boss or immune mobs.
The real problem is getting people to use these interrupts, just take a look at a w/m's scrut after a run, 99% of them are terrible, real warriors can cover almost every cast in an instance.
