Whenever a player is idle for more than x (120?) seconds Dirty Bomb calls a vote for the remaining team members to kick said player from their team. However, more often than not this vote does not pass, either because not enough people know how to actually cast a vote, or because they don’t know what this player should be kicked for.
Would it really be that bad if AFK votes would accept votes from both teams rather than just the affected one? The possibilites of abuse would be quite small since this particular vote is only called by the game itself. If the enemy team has no interest in even numbers then nothing is lost, but if there are just one or two people on the enemy team who actually care about a more balanced match they could easily help making room for actively participating players.
Also, maybe the "Kick " notifier could include “for being AFK” to better communicate this?
