Come up with the next million dollar idea!

>Implement character EXP to 50% a day at levels 1 ~ 120, 25% for 120 ~ 160, and 10% for 160 ~ 200.
>Sell infinite fatigue potions in the cash shop for $5 a pop.
>Fatigue Potions raise your EXP limit per day by 50% at levels 1 ~ 120, 25% for 120 ~ 160, and 10% for 160 ~ 200.

It would completely kill any notion of a new player base.
