This. I'd much rather seem then fix this problem than make another class that does the same thing only with a different coat of pant. They're pretty limited on what they can do right now because burst healing is so powerful.
Of course, we learned from WoW that once you get this kind of healing power creep, undoing it is painful and will frustrate a lot of players. So the path of least resistence is a healer that looks different but mechanically really isn't.
A magitech healer would be pretty cool, assuming it isn't "WHM, only with a gunblade."
