AFK surrender votes
In order to surrender, 75-80% of all players currently in the game needs to agree to surrender. The concept makes sense but there is a huge flaw in it. If a person doesn't vote, it will be treated as a "no" instead of simply changing the total amount of players present. Being stuck in game for an extra 10-15 min just because the ragequiter minimized the client instead of exiting is just dumb.
A simple fix is to change the surrender system to conclude the result on all players who actually voted.
