LOL hellgawd good luck with this proyect you only have "2" people that know well LUA and C++.... i dont have time to be another dev... already handling in 17 private servers.... lol well hope you get more experienced people... i dont think that you need to many :
NPC Creator? (Y) (N)
Item/Tier Creator? (Y) (N)
lol one or two may do that... you probably need 2 or 3 lua scripters and at least 2 or 3 also C++ scripters... glad to see that 2d wanted to help you cuz as far as i saw he is the most experienced guy in your team lol.... good luck with this...
My best wishes and hope to see some excelent releases from this
