EXP TNL Reduction - Level Cap Increase?

2.1b exp is not maximum, and never has been. It's the limit for unsigned ints, true, but who has said that it's impossible to change ints to longs? (Or for that matter, concatenating them. It's not hard.) Why do everyone think so?

Or simply cut the exp needed for lvling after 2XX in half but make the exp you gain from monsters be cut also. There's no rule saying that after a lvl up on 2.1b a higher number MUST follow, there's so many ways around that, simple, like my suggestion or by changing the system like Devil's Sunrise says, that even a kindergarten kid would not say it can't be done because of how computers work. Think outside the box, no?
