Well, i want to give some suggestion to you guys, there are some issues with the leaving your character for a night, it just stops hitting after few hours. So that leaving afk for a night doesn't work.
Second suggestion would be that you could create like autopickup settings from chatbox, there is some mu online servers, which uses this but not mu helper as you do. So that main item you wait can be picked up in afk.
Third, you could create like jewel of socket, with drop rate at some events like devil square or at chaos castle, so that they are used as well, but the percentage very low, so that you still can earn from the guys which buys gold coins.
By this time thats all, im gonna think about something. But these are the things that all of us would want from you to implement in.
So its for all of our interests
Thanks in advance.
