I never thought about that. But now that you say that I do remember the guy I was talking to telling me how he was trying to get to lvl 13 to get some achievements, so I guess in the case of the beta, it was an option for him since there is no continuation further into the game. It was making his grind easier.
At least I figured this out ahead of time.
