I love the idea but thas not gonna happen mainly because when the game was announced it was advertised as such: a multiplayer only game which yea a single player mode is what was wanted and needed but Thier not gonna do that.
Were only gonna get at least 1 more mode and some skins. I know its inevitable, but once ppl stop playing completely to us literally not be able to ever play it unless you got a group who plays often or is willing to.
