I have never been this scared in my life, I haven't played arena in over 2 weeks. I am currently having nightmares of rogues opening on me and killing me. It's not only rogues who keep me away from arena, Hunter/Melee cleaves are almost equally as scary. I like arena, I just dislike dying in openers. I dislike dying in openers so much that I can't even arena anymore. In WOTLK I never had this problem because it was actually balanced around that burst meaning people couldn't just rush in and spam CC and get a kill without risk of getting counter globalled. Cata burst is not intended therefore not prepared for meaning it's just plain stupid and gives unfair advantages to one side who can rush in and spend 30 second on CC people while being immune to damage and CC.
I don't really know what to do with myself. I have just been telling my partners I don't feel like arenaing but I think they might kick me off the team soon. I tried raiding I've just cleared 8/8 and it's getting a little boring. There are no real changes to fix anything in 4.3.2 except the vial nerf, but rogues still do crazy damage without vial.
