Chubster
If you want in on the Wargames please, let me know via Battletag, Luplis#1819. We currently only do 3's and 5's, no WSG/AB (because of the exp-off bug). We are crossing our fingers that will be fixed in 5.4. That being said, 5.4 is around the corner and I honestly believe, with the right enchants and scaling, any class/spec will be viable (with an exception of one or two specializations that are just beyond repair). Play what you love.
I think as a bracket, we really need to really look at 5.4, optimistically. If we can get a Fight Night just once during the period of 5.4 to test our enchants/healing/etc. I think we are going to be impressed how grandfathered items are no longer a hindrance but accepted. Also, new blood is important. I no longer I have to tell someone they can't gear up because that item is no longer obtainable, because BoA items with 5.4 enchants will be without a doubt the new BiS. Talk to people, be kind, and be helpful. 29's need new eyes in the sky.
Hope to hear from you soon, Chubster! Don't be discouraged.
