In PvP, if you choose to do so, you can leave the game you are currently in while you are in the middle of a fight. The score remains as it was, no points scored, and your opponent does not get a kill. The punishment: 1 death, the same thing you would have received had you stayed. This can quickly ruin PvP if not addressed. Free for all has no meaning when both sides leave when low on HP. Players use this little "strategy" of theirs to win in FFA because they rejoin the game right after leaving and get a kill on their injured opponent. This "strategy" needs to be fixed.
