If they need a balance why not have an "active" spell list?
You can learn all the skills/spells you want (or a limit based on the skill level)... but can only use a certain number of them.
That way they can avoid their "Rogue can keyboard their way through fights" issue.
Honestly it doesn't help that quite a few skills are either useless (Hello Fortitude after the early game) or extremely build dependent.
