I don’t see what purpose it would serve to remove a class, though. I don’t enjoy mystic at all, but I wouldn’t remove it from the game.
I would certainly like to make a bunch of changes, though. Assassin and Archer/Huntress definitely still need some work, and I’d really like to see wismod on necro. I’m quite happy with the priest/pally balancing, but the sorc change feels pretty meh to me. And yes, I’d like to see another katana class-but I’d rather my bow classes get some love first.
