About two weeks ago I purchased MOP. While I'm enjoying it very much in the general PVE environment, I must say, the dungeons are so easy, it feels almost pointless. As a monk tank, I just aggro some enemies and stand still for 5 seconds while team mates kill them.
It's so easy that even when 2 people disconnected or I wind up with some rogue asshole who is under the impression they are the tank aggro'ing everything, can't die.
Of course this is just classic mod, will dungeons become an actual challenge in heroic mode because at the moment, well, they kind of suck.
