STOGEGive some sort of short rejoin ability if you leave the server, just in case you time out. Something like MvM.
Much better than just ending the game, could even do something similar to Rocket League and substitute in a BOT until the player rejoins/connects.
Could also do the dota thing and give like 2 minutes then announce that it's safe to leave
A rejoin system like the one in csgo would be nice. Also maybe a sub system on top of that for people who fail to reconnect. This could potentially improve search times for people too.
also does someone know what voice codec tf2 is using right now? there shouldnt be anything holding them back from using the improved codec they have in csgo
