What would you do if you were the game developers?

A mixed class is unnecessary.

To each their own. I've always played with battle mages in Heroes of Might and Magic III. If Knights had skills that made magic unnecessary, I would agree without question, but right now, we have some kind of absurdity. Class abilities are too vague and simply laughable. And if they come up with something unique for the Heroes of Might and Magic, it will again be some kind of shout or something similar. Consider it the same magic, but with a different name. The developers have a serious lack of imagination.

Yes, and as an aside. If I were a developer, I would commit seppuku first.
