White Mages definitely fit Paladins closer, though I'd still say they share the most similarities with a Holy Priest in the end. But yes, White Mages are the kings of healing output, at least in the AoE and burst healing sense. Single target healing and mitigation is the Scholar's domain. Overly simplified, but I'm feeling lazy.

And well... I suppose an inexperienced healer appreciates the Faerie being quite good on its own. That said, not having the tools to adequately answer all situations until 40 is a bit annoying.
