The game is way to Easy until you get to End Game

I sincerely hope he doesn't. People need to learn how to play their classes, not bumrush their way to endgame and have no clue how to play them.

What, you think people learn a lot about how to play by doing FATE grinding? It's pretty trivial to get to level 50 without knowing anything. Also, leveling up doesn't teach you how to play. How you play at level 5, 15, 30, 45, etc. has little to do with how you play at level 50. Stuff pre-50 doesn't really prepare you for the mechanics-laden madness of endgame.

Most critically, an intelligent individual will learn how to play correctly even if you give them a max level character right from the get. Less intelligent people won't, no matter how much you handhold them, so I don't even know what your argument is here.
