first: i cant believe there are still new threads created because of this. hi #1000.
second: the "hc dungs" were easy before if you had good and coordinated people. bad and uncoordinated people did'nt like this and came crying to the forums. blizzard listened, and now pugs have it easier. now they come crying again? what in the hell? and IF you found the "hc dungs" hard before the patch, then you ARE the clientel that blizzard changed things for. stop crying. there was no challenge in 5 mans before if your group was decently coordinated, there is no challenge now. nothing really changed. the patch only caters some puggers with bad luck in their random groups, and that is OK.
you did not talk about raids, that would be a whole different story, though. you will find challenge in raid-hardmodes, even after 406, so no worries.. ;-)
