There is no need for this much of spells for healers

[Aravell]

As an outsider looking in- Spells just needs more trimming down; and perhaps let some of these spells become combo-spells (the lesser needed ones) or better yet, turn some of them into passives.

I don't know how Spell-casters feel about that in a broader sense, but whenever i get glimpses of a friends or FC members spell bar; i tend to vomit a bit, because it's super absurd to have that many spells buttons on the UI screen.
(it reminds me of old school Perfect World where a player had 38 to 43 spells to manage.)

No, there's no trimming down needed. Casters are very different from melee after all. While melee jobs tend to focus on combos and branching actions to get you thinking, caster gameplay tends to be more methodical and much lower APM.

Instead of pruning spells and adding combos, I'd much rather see each of the spells we do have be made more meaningful so planning is useful and our choices matter. That would create a much more satisfying caster gameplay loop rather than forcing a streamlined path of spell usage via combos.
