Some thoughts:

Shield Bash and Shield Swipe - Off of GCD. Give both a minor cooldown (8-15 secs?). I would rather they have a cooldown and fights retain a smooth feel than have to choose between cancelling my combo. It forces unnecessary prioritization over our loan combo.

AOE - Not a huge issue, but maybe add an extra skill or give us Overpower. Warrior's get Flash...and we get...Skull Sunder from them?

Invigorate/TP/MP - Why do we, one of the lowest damage classes in the game, have to pace ourselves in DPS? Huh? Warriors have access to Invigorate, but we have no way to replenish our TP? I understand it's the cross-class abilities, but this should be addressed. Food for thought, allow us an ability that lets us USE OUR MP FOR SKILLS. Give an ability that depletes MP and maybe boosts potency of said skills. Kind of like how WHM have Cleric stance. I'm sure everyone's imagination is working out just how well this could sync the class and it's abilities (Riot Blade).
