Please... The game is currently balanced enough to have fun, and the class you play doesn't matter. After this patch, hybrids will die, with all str biased builds (guys like Mendro, Butan, Nikodin etc will have to respec to another build, which will make those play styles die) . And you will buff every guy with 21 agi, aka archers, lancers, rondelmy old friends , ninjas, etc ... -> already pretty annoying.
Having a new formula is fucking cool, but not in this way ... both agi and str should get advantages. As Stevee said, damages from WPF should be removed or nerfed to avoid another nerf, but this time on ranged's accuracy and speed.
Btw , nerf rondels, with or without new formula.
