This post comes a bit late, in fact it has been over 100 days since KOF98UMOL has gone live on the North American Servers.
I have a guild on Server 1 called ComicFight! I spent all my diamonds leveling up early, and now I spend my diamonds on equipment chests and donating to the club.
I havent dropped a dime on any of the games, so don’t expect to be number 1, but we have enough people to get good rewards.
