I like this xp boost idea actually. I'm working full time, I have a fiancé and responsibilities. I have quite a good income, but time is of limited supply. I don't understand why my money should be worth less than your time? I feel, in this way we're actually on a level playing field for once.

Now, I don't even think I'll be buying any XP-boosts, I always enjoyed the way to max level far more than actually being up there. But in principle I think it's great.
