Lustrate didn't really need a buff, but it's nice I suppose. It also comes at a time where Warriors are more viable end-game, so that's a pretty huge buff. (5% of a 9000 HP tank is a 450 HP increase on Lustrate; it's an extra 350 HP on a 7000 HP tank)

Medica II is now more viable for solo healing Titan; as you won't be a threat monster in the early stages now where a single Medica wouldn't cut it and Medica II overhealed. It'll also be nice for solo healing Turn 2; one Medica 2 will take care of the raid damage for double the amount of time, without the added overhealing.

Cure III will be great for Twintania Fireballs now; as before people would sometimes be out of range of one another. The increase from 4 to 6 also makes tank and melee DPS healing viable will Cure III.

I love these changes. I'll continue to play both my SCH and WHM.
