Thanks for the feedback guys.. so helpfull!! I have taken all your advice into consideration and decided to go for 3x rogues..

This isnt my first box team.. i have 4x shamans..
As you say with rogues I can pick my fights setup CC and vanish if i get in shit! I will nearly always be running with my bro (Healing priest/pala) and mates.

Going to roll them out now and let ya know how i get on..
