It is a bad idea, the last thing we need is another game to automatically distribute stats. Most MMO's do that crap now.
Auto level would be good for the easy mode only. From "normal" and harder it should be up to the player to make such a decision. On the easy mode, there can be an option to auto distribute stats for a specific class. Even then, I personally wouldn't have it if I ever made a game (which is unlikely).
