daggers and raid bosses

i remember back when your leet new dagger skills were announced ppl were freaking out that you would able to 1 hit raid bosses with a bit of luck, im gonna assume that doesnt happen since the farmers arent doing it but how do you guys do at high lvl raids?
do alot of damage from behind?
pull hate?
is it even worth useing skills due to the high mp cost?

I believe that NC set it up so that Raid bosses are immune to those dagger skills...pretty much just like how you can't 'debuff' them either.

From what I've seen the damage from a dagger is pretty useless, their skills just don't land enough and use too much MP to matter.

As for debuffing, thats only epic bosses, every other boss can be debuffed.

Is that raid boss in the hero rift considered an epic one cause I couldn't hex it for the life of me...

Rift RB can be debuffed.. I've managed to arrest it with a mid 60s SWS :P

Daggers do great damage on RBs..

The time when you could Leathal an RB was on the test servers in Korea, it was fixed before it came on US test servers.
