With the changes to warrior's shield block, the only class capable of avoiding a shear is a paladin, I wonder if blizz thought this through....
Now, dont get me wrong, I've tanked Illidan as a T6 Prot Pally, its not impossible, and especially with the new changes he'll be easy enough to handle, but no tank other than a pally being able to tank a boss seems to go against what blizz is working for. I wonder if they removed shear with 3.0.2....
