WHM
Medica is now Curaga. Medica II is now Curaja. Yes I hate the name Medica.
Also Esunaga is reality and Benediction hits the whole party but has a longer recast time.

SMN
Contagion is now a SMN ability that consumes a stack of Aetherflow when used. Bane, on the other hand, doesn't anymore and costs 150 MP.
Garuda's Contagion is replaced by 'Ill Wind' which inflicts Miasma and Bio on a target.

SCH
Fairies will now sit on your shoulder and/or head while idle. Yaaaay!
