Having something goofy can make the game interesting... Only 1 or 2 classes having something goofy placing them a good 10-15 GR levels ahead of others is silly. The most "goofy" thing wizards do is combine their set-bonuses to create a 14000% weapon damage per second time zone. Which sounds like a lot more than it is :/
What makes it worse is the lack of gear-requirment to play heal monk.. Every Wizard/DH/Crusader can spend 2 hours gearing up a Monk (not difficult just ask the 3 monks currently in the group to give you gear they don't need) and play healbot in GR's multiple levels above what their 1000 hour play-time full ancient main could.
Coming into the season now might not be as bad as joining in at the start. At least it wasn't 3 out of 4 people playing a Uli monk when only 1 works in a group.
And Blizz pretends like they designed the game to play with friends. In reality, you end up strait to chat channels looking for random players while having to decline clan mates due to the classes/specs they're playing.
