I'd like a melee heal, withs fans as weapons maybe...
It would have several combos (like melees and tanks), one for DPS (maybe with a dot / slashing debuff), one for Mana/TP recovery.
And a system of "steps" similar to the ninja' mudras; with more possibilities maybe, that would generate various buffs and heals. And to avoid the problems Ninja is facing currently, I'd made those steps part of the GCD, but using them would bring the GCD down to 1,5 sec, like the RDM melee combo. It would make it a bit dynamic.

Well that's my fantasy haha. +20% potency when there is a bard in the team.
