Penalized leave on repeated leave. Let's say a user leaves a match or is afk a full match 3-4 times within a set duration, I feel that the game should either force them back into the match if they try to run another one or should give them a 4-5 minute timeout. This way players aren't just leaving because they're losing and since it'll be within 3-4 leaves it won't be them just "leaving on mistake." If it's a disconnection issue having them tossed back into the match would solve that accidental disconnect, if they're getting repeatedly disconnected they need to fix something.
