@CtrL4LT How do you know the AFK player did not get DC'd? It does happen. I think a permaban for being DC'd is a bit extreme. The 10 minute ban was avoidable, it is not the end of the world to sit there for 1 minute and let your banner expire.
In my opinion, the benefits of having a leaver penalty far out weighs taking it away. I can frequently come in clutch and recover banners. Before they implemented the leaver penalty, I would frequently squad wipe the team who downed my mates. Have plenty of time to respawn them and get their loot back.. Only for them to leave in a fit of rage. Which would leave me in the difficult position of playing through a ranked match 1vs3. If they would have waited just 1 minute it could have translated to a win or at the very least more kills and more RP.
