Guild Wars 2

There needs to be harsher dishonorable penalties for people who leave games. First of all, there should be a stat labeled games played and games left, so its obvious who are the dishonorable people. Second, you should be banned for the day after leaving 3 matches, and banned for the week after leaving 5.

Check patch notes. There is dishonorable debuff. Suspended from rated matches if you get 5 stacks (lasts up to 72 hrs).

If 1 player doesnt join, the client should cancel the game or end it in a draw instead of forcing an afk to join the game
