if you are running on WotLK client and patch 3.3.2 (of course you are), there wont be a patch up, if not there would only be a client update.

the title mostly come from achievement.

And don't bother tanking unless you got around 30k hp, people are going to whine. run normal Trial of the Champion (5 man) until you get black heart, that is one of the best tanking trinket heroic wise. another one dropped at Heroic Azjol-Nerub.

Get more Gear from Heroic, get T9 with badge purchase and dont forget the ilvl 245 helm/shoulder from the badge too, if you got a lot of change to spare, get the blacksmith iLvl 261 bracer, belt and greaves.

by the way, which class are you playing?

Very Soon™

do normal 85 dungeon?
