So our guild was trying 10-man Ulduar last night and it wasnt pretty. Ignus took our lunch over and over so we gave up and went to the apothacary and that huge guy (cant remember his name). We were rocking for a bit and got at close as 9% but alas, no luck. 100g in repairs and 20g in potions down the toilet.
10 and 25 man Naxx went much smoother and my acquisition of the Dying Curse just about maxed out my Hit, leaving me with only a .5% chance of missing, and it procs like a mofo.
