Please improve Farm as well since as soon as you reach level 30 in Farm there are no longer any reasons to level farm up. So add seeds like 15min seeds, 30min seeds, 45min seeds and so on...
Re-make Battle-Ground Level System, Reduce the amount of Lag in World Boss, Increase the amount of times you can go in Catacomb and MP dungeon and have a better option for chats such as no System+Info appearing.
