I am a Galkan Whm, I think this actually works nicely at times. The cast time of this ability is near instant, and with high HP I can really give out a decent sized cure for no mp. Not only that but you can use this when you are silenced, instead of waiting for the echo drops to finish loading up. There have been fights where half the zone seems to link and you find yourself with no mp, 2 hour used up and this really can be the difference between a life or death for a tank. PLD FTW...Martyr to take them out of the red and then Devotion to fill up their MP tank and they can keep themselves going long enough to give you time to rest up a little MP to keep going.
