The healing roles in this game are actually beautifully balanced, to the point where if I pop into 8-man content in a pug and there's a second white mage, I groan.
Two white mages or two scholars are a terrible matchup. One whm, one scholar is fantabulous.

I have tried scholar and cannot get on with it, but my static scholar feels the same about whm =P We are a dynamic healing duo~
