Well the weird thing about UK is that the best advice on the first boss is to ignore the tombs unless it gets your healer or tank. I found that healing through tombs was very viable.
I really feel like I am 4 manning these runs though, because my hunter is not currently hitting even 1k dps. His gear is much weaker than the rest of the team and my macros are sitll not finished on him.
I do believe I may try DK and also Gundrak, have to figure a better strategy for the first boss, my dps is not high enough to just nuke him I think.
