Have Perfect Balance and Masterful Blitz be one button. No reason for then to be separate as you would never use PB again before Blitz.

Get rid of Forbidden Chakra and make Enlightenment do damage to first target then reduced damage to all remaining targets.
Really no reason to have single target and AoE versions anymore.

But, then, if they consolidate buttons too much then people would see just how simplistic the Jobs really are. Lots of buttons gives the illusion of complexity.
