Exp/Level 1 - 200

Yeah, the exp to next level curve gets extremely steep due to the formula becoming an exponential function instead of having level be the base of the exponent in the old formula. Here's a comparison between the exp it takes to level post-BB and currently in gMS, with 160-199 values probably being off by a tiny bit, like a few hundred thousand:

Overall decrease: 37.58%
1st job decrease: 68.76%
2nd job decrease: 75.42%
3rd job decrease: 63.11%
4th job decrease: 37.21%

Looks like with the removal of party 2x exp, it seems like it'd actually be even HARDER to level up now in 4th job, assuming the changes in monster hp/exp is consistent with the massive damage upgrades in regards to exp rate. Also, more trivia: post-big bang, the exp it takes to do 199 -> 200 is higher than the exp it takes to do 1 -> 153.
