Ah thanks, I think I got it now. The mpen essentially is applied only once, but the AP is applied everytime you hit someone.

Against someone with 1K HP and 100 mres 200 magic dmg per attack is going to hurt more than 100 magic dmg with 50 mpen. I mean even though the 200 dmg has to cut through 2K effective HP that takes 10 attacks. But with 100 dmg against 1,5K effective HP (1K with 50 mres because you got 50 mpen) that takes 15 attacks.
