^^^^^^^^^ explains everything- i've been looking for one
What is the suggestion? A way to remove players from a game that they already have accepted. Why? Not nefarious or anything, just my hosted games are usually custom scenario and take forever to fill, that makes it so players in the lobby end up not being on for over a month, or just a week or two and racking up a 100% bootrate. These players always get booted first turn once the game finally starts, and due to the custom scenario a large power vacuum, which is not ideal and causes many others to surrender, and the games get ruined. I switch the AFK people to smaller slots to avoid this, but it's a problem nonetheless, even in just normal games, like team games a team will have a missing teammate, or just a normal FFA not having the desired number of players from before the game begins.
The real suggestion is this- If players rack up say a higher bootrate than the prerequisite, or a different set one even, the host can remove them from the game.
