I've ranted about my least favorite enough times that I'm sick of it. But I imagine and hope that no one is actually keeping track of what I say, so fine, again.

If it were really "use it or lose it" I'd be fine with that, but unfortunately it's more like "risk losing it every single time you use anything else at all," making it very frustrating to make a magic user. "I don't need to use magic here, but if I attack I might lose magic power so I'd better waste MP on a useless spell" becomes "well, now I'm halfway through the dungeon and out of MP. Now I have no choice but to lose my magic power." That would be a flaw. The fact that the one and only time I could stomach going through that game I didn't know that this would be an issue and actually had two mages made it even worse. I would have been enraged had I actually paid for the game.

If you like the game, fine, good for you. But don't sit there and try to tell me that the system was well executed. It was not.
