I'll have to do a playthrough myself and see how the balance is. As it stands, I might have made the enemies too quick- especially Dolls, Dolls should be much slower, particularly by this point in the game. If you're having to do excessive grinding, that's a sign that I really messed up the balance and need to give it another look; I'll work on that tomorrow.
Gear in particular is probably too expensive and I need to give that another look. (And Accessories need to be better- I'll work on that as well!)
EDIT: Started work on that. Enemies will spawn MUCH faster, and you're going to love the new thing Hunter is about to get.
