Loss Prevention from D/C players

I was hoping to play a quality 5v5 duo que rank game with a friend of mine to only conclude that the majority of my games were dealt by a bunch of d/c players who were either rage quitting or simply having a shitty internet. Riot needs to implement an end to this. Sure, there's always loop holes. For instance, the people who purposely lose because they're playing a "double" account. Quite honestly, this doesn't mean shit if they're not progressing in elo points; instead, their account that purposely d/c's should double the loss points. There's no justice in playing league with a crappy internet, if your internet sucks, you probably automatically suck as well and you deserve to lose points, not those who actually try. This isn't about "oh, you just can't carry hard enough, " this is about being fucking handicapped and its absolutely unjustifiable. I can handle kids dying on purpose but this can be stopped under Riot. Anywho, I'm just putting the word out there, and I don't even know if this message will make any sense, but it's not my fucking job to figure this out.
