Botlane was well ahead, as was our team

Until our Riven, who had laneswapped from top to bot, DC'd.

Within three minutes: Botlane turret was gone and the enemy had secured dragon. Within five minutes: The enemy, who had been down two kills, were up two kills. Within ten minutes: The enemy had claimed two more turrets and won as many teamfights.

Why. Why, after all these years, has nothing been implemented to soften the blow of an AFK/DC? Is it so low on your priority list? Do you not give a frosted FUCK about the PLAGUE of fucking people getting disconnected and instantly relegating their team to a loss?

I want a fucking answer, not some bullshit rhetoric from the caverns of someone's ass. This is ridiculous.
