However, the ability to penetrate magic resist is slotted into a spell, meaning its taking up space and rendering him less 25% of damage output. So someone like say Brand who has 4 spell slots all dedicated to dealing damage will make up for not having that 30% mpen. So having a spell that gives you penetration will not necessarily give you a leg up on people who have 4 spells dealing damage.

I do see your point, % MPen is useful. But again as I have stated above, his spells base damage and ratios need to surpass a certain threshold before I can deem him equal with what I already have.
