First of all no offense - cool idea

but we have duel(1v1 mode) ? and private lobbies removed or idk it existed in this server.
at this current situation of fgunz they have to more focus on fixing crashes cus since last 6moths crashes made players mad-bad-gone, everyone started to hate gunz and gunz is memories of childhood we don't want to lose it.

For me its a NO sorry.

I also heard they developing fgunz bot so this might comes under bot stuff? challenging in discord / 1v1 rank / its public and also people who are not in game they can check players challenges.
