Been there dude, I actually canceled all of my account for a month then went back and gave it another try but I wasn't wiping on heroics I was wiping on normal instances and it really really sucked so I canceled everything. But when I went back I took it a bit slower and got some decent gear in pvp and rep and got my enchants and whatever else I could get a hold of and now I can do any instance and I am working on heroics. I have cleared UTG and Nexus many times but I am waiting now for 3.2 because of the emblem change it don't make much sense running for heroism emblems now.

My tank is a Druid.
