Surplus EXP is just bad advertising and marketing. Really, who wants to play a game where you (yes eventually) will pay a monthly subscription only to be limited to doing 8 quests every 36 hours and then hitting a FATIGUE so you gain less and less exp/sp till you just wont be able to progress. The purpose is to promote the game and sell it. Not tell people that if they have a weekend to dedicate to their favorite thing to do in their favorite game.. They can't.. Oh cause if they play too long they are punished. lol

This is just an embarrassing feature, really.
