Don't play a sorc, much less as healer.
Sadly, for some reason, at ZoS they decided that sorcs have to be the "below-dummie-IQ" ultra-starter class. Thus they made them more and more boring and toggle based, to the point some builds have 3 double bar abilities. A 5 (five) buttons class, that bores to tears.
Plus, if you want an healer, templar as of today is what you want to roll. Warden too, maybe.
