How many skills is too many?

[Nixxe]

Imagine if you had Cure, Cure II, Cure III and Medica, while pruning away Medica II. If you use Cure, then Cure II. When you use Cure III it is a large single target efficient heal. If you use Cure then Medica, then Cure III, it works like it does now. If you use Cure, then Cure II, and then do Medica, it fires off an AOE regen like Medica II did.

That sounds really annoying. It's not even a question of skill at that point, but of rote memorization of various combos.
