After TENS OF MINUTES of work I'm ready to release my modification to Brave New World. This is deliberately designed to be harder in a "FF3usME stat hack" style. @seibaby helped a bunch.
ATB formula changed so that enemy ATB fills twice as quickly.
Esper Levels that grant HP now grant half the HP
Warp and Warp Whistle made 33.33x more expensive.
Lowered ATB multipliers for slow/normal/haste by 5 each due to an overflow error causing hasted enemies to have very few turns
Made the timer for status ticks constant, so that they are no longer affected by other status effects like Slow, Haste, Sleep, and Stop
