This thread never sleeps....
It's not that we don't ever use Cure I/II, but if it can be healed through with regens, that's more dps up-time for us. If I'm ever casting cure, its because I have to. This isn't necessarily the way we're supposed to play white mage, but this is how many people do.
I would also point out, the required increase of cure usage isn't the only complaint people have about this new system. Read some of the other complaints people have, there are 200 pages of them.
