I think even if they revert the Bones quest back at all, it should be 250k-300k maybe. I understand how 500k was putting too much money into the game, but they also did nothing to remove the money that was already made and exists. If they did a daily limit on the Bones turn in, that would also help smooth out huge zuly amounts in the game.
The Clown quest definitely needs to be changed though. Level 50 is already high enough to just go to Kenji Beach anyway. If they want a level cap on this for some reason it should at least start at 35-40.
