As far as I can see this might help me get into Gruul and Kara. As far as gear planning goes.
Step one: run through as many heroic/normal TBC instances I can and get as much awesome gear as I can.
Step two: get all decked out in what PvP/Arena epic gear there is by the time I reach the Level cap I'm level 42 by the way so I may be totally wrong on this.
Step three: Use my PvP/Arena Ret gear in Gruul and Kara as a DPS role then inevitably be forced to buy the healing tier 4 gear so that my guild will let me go to Sunwell Isle, Mnt Hyjal, and Black Temple. that way I can go around and buy the tier 6 Ret gear then go back to Arenas/Bgs and let loose Pwnage that the alliance has yet seen from the class that they once considered theirs.
PS if my dream is overplanned tell me. If I should just skip the raiding gear and wait for WotLK to get some new gear, tell me. And If you have any suggestions/edditions to my plan..... Tell me.
