If you think that this is the way that Gunz will survive why don't you make your own server. Sounds like a great opportunity to me. Just hire some DEVs and there you go.

As for FG, guys worked 1+ year on this update. They wont change it anytime soon and even if they change it they wont take back to "original". IJJI was a great Gunz server but things change.
I wonder what you think IJJI would've done better than FG if it was still alive. Gunz is 12 years old game overall and i doubt that IJJI would stay to that "original" game play.
