Suggestions:
1) Remove custom effects/pets. (I know you already said you will).
2) That scroll which looks exactly like a 2nd premium: no, please do a favor to yourself and completely remove it.
3) Reconsider some skills balances and make some polls about them before implement them for sure. (That 2nd Bicheon Passive is a joke, Bicheon doesn't need defense, only a little damage buff, nothing else).
4) Implement a system where Traders only get max amount of Coins if there're 2 Hunters in the party, otherwise Traders would get half amount of Coins.
