I'm just sick of having tanks do Heroic: Halls of Origination, say "I'm doing Rajh first" - then either RQ'ing cos we disagree with him or he knicks off after Rajh, leaving us with no tank to do the other three bosses, which some of us need gear for. /sigh
Also, the sheer rubbishness of tanks coming through since CtA came out has been hilariously bad. I had a tank with just over 100k the other night, and he then votekicked me because I was pointing out his flaws!
Honestly, RDF has devolved not evolved.
