The problem that I'm noticing is that stats seem to scale 1:1 with their effected stats, like melee attack, accuracy, and evasion.
It seems to be 1 dex = 1 accuracy, which is not how the old formula worked at all. This makes things with higher evasion values much harder to hit.
It's possibly a bug, but there's not much of a way to really tell as of now. It very well could be that mobs need some changes in their stats.
