As soon as a player's nat type becomes yellow/red, other players (all of them or only enemy team) should be able to votekick against that player, so the laggy one won't ruin the match.
Players with bad connection have advantage as this has a p2p connection.
This way, a good player with green nat type won't be kicked and a player with bad nat type wont ruin other player's game. Also, players with bad connection shouldn't be able to vote.
I'll bring it up to the team to consider, but once DS come this shouldn't be a problem anymore so this feature would most likely be obsolete. And with vote-kicks you always run the risk of players kicking others for trivial reasons - which isn't something we want to see happen. So maybe a vote to forfeit/exit might be a more approachable solution?
