I think I may have to start a whole new character, just to learn this all from the begining. I went back into beta over the weekend, and aside from getting owned by a level 11 attacking Ogrimmar with 65k health cutting through my Cata gladiator gear like it was nothing, I was at a complete loss.
I read what you guys are saying, but I couldnt see the big picture I guess. I tried looking at talents, tried configuring action bars for spell priority. It all was a mess. I went to the dummies, and tried working on a rotation, it felt jerky and like I was waiting at times, panicing because something was up while casting somehting else. Maybe because I am only at 85 I guess.
I do think being at hit cap is going to be a must. But I just don't get the big picture right now. It mostly felt like mashing buttons as soon as they proc'ed. If I am going to be stressed over having to make sure I hit proc's at perfect timing, and have to rely on Add on programs to play for me, I may as well quit, because it is no longer me playing the game. Its Shadow Priest whack a mole.
Tried heading off to the new zone but all I saw were corpes. Looks like its being turned into a PvP amusment park. I will buy Mists. I will level my main to 90. But I will probably just explore, and do the dailies until my eye bleed.
