I'm not saying this simple arcane caster should be bad, but I'm saying if the point of it is being simple. Then, it should be simple. And if the point of it, being a caster, then it should be a caster..I don't neccessarily agree that a simple caster should act as sort of training wheels for the "real" spellcaster.
It should be its own class that does what it needs to do to be a viable class among all the other others and uses magic, filling the niche of wizard/warlock/sorceror/witch/occultist in theme, but being much easier to build and run in practice.
What's the point of making a simple arcane caster that is not simple, not arcane, and not a Caster?
