I used to play as WHM a lot right up until around 3.1 when I decided to give SCH a go for a while.

WHM is a play style that forgoes utility for strong healing output and HoTs. Medica 2 and Regen and Asylum stacking is what allows me to stance dance without worrying too much about the tank HP dropping too quickly. This is further supplemented by Assize and Tetragrammaton and Benediction to use during OH SHIT moments.

It was a great healing class to start with and I still enjoy it from time to time. Although I play SCH and WAR more nowadays, I still have an affection for my white mage...its just a shame that for savage I mainly tank as I enjoy healing much more xD.
