The issue I run into on my server, is there are TONS AND TONS of Naxx Pugs, but most are very, very terrible and you'll spend an entire night on 1 boss. I took my main shaman as resto (with decent gear, crafted epics and BoE's) to Naxx 10, and it was a clusterfuck of epic proportions. So for now I stick to gearing my toons in crafted epics to meet some miniumums to get into guild alt runs, or try to pug with more respectable people. Trouble is, there are many more bad pugs than good ones. Everyone wants to be carried. I don't mind doing the legwork, but I refuse to carry idiots that just want PURPLEZ.
