Hiver I like your idea of Cleric.
Wich is one class I would like to create. (Paladin would be nice too)
But picture of health doesn't work if you are not putting anything into warfare.
As a starting talent I wouldn't add it, since many players view the Cleric as a buffer / healer.
I like to use it as a fighter, a front melee with some reliable heals or buffs...(not as strong as my melee in that case)
I would add something like bigger and better or all skill up for this preset. With this current system in place.
My actual suggestion is:
A specific talent for a specific class. Especially created for each preset.
But it seens larian likes hybrids builds so, I don't thik this is going to happen.
