Same as others with DP/Deadeye and duelist. But I also like to disc early in a fight to give me a bit more time for end regen and then I have a full counter attack left.
I use counter attack on enraging mobs that are not cornered, when the mob enrages I move to stand near to MA and hit counter attack. My plan is that this will help mob stay facing MA during rage and turn less often. I do however have to be careful to turn attack off before moving to front of mob, and keep an eye on disc timer in case it runs out before mob finishes enraging, otherwise i luck like a daft rogue
