They're certainly not going to nerf DPS casters mana regen *at all* because to do so would make them unable to compete with other classes that have infinite resources.

Once again the game is balanced on the backs of healers, which is poor design, but hey at least I'm Shadow now.

PS. You guys should do something about the mana regen system, and do something to make mp5 better - it's currently a trash stat.

We consider Replenishment mandatory. What I mean by that is we assume that you have Replenishment available to your raid. It is technically possible to go without it, but you will need to overgear the instance or otherwise compensate for it in other ways.

That doesn't mean we will or will not nerf Replenishment. But we don't want it to feel optional (assuming you are in reasonably challenging content) and nerfing it too much might have that effect.
