Again, these are all valid points:

The game is too easy without large challenges added for fair comparison of ability use.
Mages currently cannot run out of MP. Ever. At all.
MP Regen + Abilities = Overkill

However, these suggestions on how to remedy that are just as counterproductive as the current situation. The goal here is striking a balance, which the removal of the system altogether simply does not do. MP Regen solves as many issues as it creates, and you're proposing that because we took two steps forward, we take a step back. I don't agree.

The implementation of MP Regen threw off the balance of the game, and it needs to be recalibrated by taking another step forward. I'm not willing to go back to the needless frustrations that lacking MP Regen caused me whenever I switched classes or walked more than three minutes from an aether just to make the battle more challenging if we can achieve the same re-balancing without adding the needless frustrations back.

Am I getting through to anyone? At all?
