Similar to overwatch's version of this gamemode, but with a few differences. You select the gamemode, and you select how good the bots will be on a scale of 10. 10 is like diamond-immortal bots, 1 is iron. You also have bots on your team and could select how good THOSE bots will be.

Its just like a normal game, and you go till round 5. Maybe you could also select the map? Idk. I feel like this would be an amazing way to warmup if dm is getting you tilted.
