My tank is actually already 80 and has some Naxx10 gear.
I have been doing the WG for sure, our server is some how 2:1 ratio and alliance don't ever do WG except on reset. (Aka they never own/win/controll it.) think current standings are like - Alliance: Keep Defended: 11 /Keep Captured: 347
Horde: Keep Defended: 489 /Keep Captured: 374

Ret pallies so far have been great on healing. though i do not know if i will end up getting bottle necked in heroics. (done all the dungeons up to 79 no problem)

Will do 10games a week min for arena even if not geared.

**Don't really want to random BG without good PVP gear.. scurrred of flamers =l**
(tho people have welcomed n cheered me in WG since 77 =p)

I guess I can try to do a few ICC / TOC on my Tank and try to get/buy gear. (but gearscore will prob hold me back unless paying)

Thanks for input guys
