They are using the levels of 50-60 as a tutorial section for the new abilities they are throwing into the jobs. I've been sighing all the way through as the last thing I was interested in coming back to playing my paladin (king of "keeping it simple" gameplay) and finding out they are adding more abilities because "it's not challenging enough". How about making the encounters worth their play time instead of worrying about how complicated our rotations are? We aren't playing dance dance finger revolution, we are playing a MMO RPG where situational awareness is key.

Well, unless the idea for situational awareness is supposed to be "Oh, on my rotation I got to be flanking the guy now, so I'll move over here..." instead of "oh, the boss is going to do a swipe in back of him, maybe I should get away..."
