How? I'm barely hitting 180k when bosses die. Are you solo tanking, spamming /sit or what? Because I just can't see how can you push such big numbers. Especially since you raid 10mans, and I do 25H, where bosses hit harder.
Also, I assume your Jin'rokh numbers included you standing in the pools whole time those pools are up? Because I never broke 200k on that fight, but again I was taking 3 out of 4 tank throws and never stood in the pools, since space is very limited in 25M.
