The idea is that if MP was actually in short supply, the increase in MP regeneration would be significant as long as you are using MP for something else, since it would allow you to cast more spells/abilities/etc. However, currently you get a surplus of MP before you even get rank 2 of the mutation, let alone rank 3, so increased MP regeneration doesn't matter for that. So you're effectively just getting a small boost to HP regeneration, specifically one that is too small to matter, and rank 2 and 3 of the facet do basically nothing.
In spite of that this still manages to be the second strongest tier 2 facet after nightstalker, so you probably don't want to buff levels 2 and 3 without commensurately nerfing the effect of level 1. I would hate to see partial guardian spirit, so I'm not sure how to approach that issue...
I suppose you could globally nerf max MP to make MP regeneration in general meaningful after the first few dungeon levels, which would both fix levels 2 and 3 of the mutation, and nerf level 1 into something more reasonable. I think that idea would be hard to sell though; to make MP regeneration meaningful I think you'd have to reduce max MP pools by
at least 50% by the time people are in Lair (MP pool size on D:1 is fine), and even more than that later. Not many people would go for that.
