I, personally, don't have a problem with there being other healers in the game. Heck, if another class has a healing ability, good for them. But MY point is, White Mage should be the BEST healer in the game, since the very nature of it's class is, in fact, healing. Seriously, I'm not gonna flip out if another class knows Cure. But the higher leveled healing spells (Cura, Curaga, Curaja) should remain WHM exclusive. Nothing wrong with having another class as an off-healer though. In fac,t really, every mmo has classes that can act as off-healers. So, why would anyone think people are gonna lose it if other classes in the game can heal? Gimme a break, lol.

Other classes being able to heal - Cool
Other classes being able to heal as well as a WHM/Priest - Not cool

Just my $0.02 on the subject.
