BDM is great game, but lack of feature. if i can give suggenstion :

GUILD:

1. member list can sort by CP, Name, recruit date, etc

2. add guild rank

Chat :

when open chat windows, it should guild chat first shown, not normal chat.

so if we at node war...leader and officer easier to command from chat. or you can add Voice chat command at game

maybe just this from me...maybe other can add more.
