Well when FCoB was still new, Scholars were recommended to contribute in DPS numbers, only switching out to assist the WHM during certain mechanics.
Maybe they'll tweak Alex so that it's impossible to solo heal majority of the encounter (I doubt that), but otherwise if you play a Scholar and you wanna be raiding while its still new, you'll probably need to DPS more.

If you're really really against DPSing as a healer, I highly suggest you either play a WHM or an AST (Speculation only, but from most info seems AST DPS capabilities are even worse than a WHM, rely more on cards to buff team members).
