Solution to D/Cs and affecting rank

The chance of a d/c being on your team or theirs is about 50/50, HOWEVER, I have a solution that might work balance it a little.

Since a reduction in penalty will never happen, a LOSS PREVENTED status should occur ONLY if you're at 0 LP and going to be demoted. This way you still have to fight your way up and it doesn't make it easier to get promoted, but you won't be penalized so friggen hard for a D/C.

Here's why this should be implemented.
-Normally 1 loss and 1 win net you a few LP, D/Cs are 50% on either side, so that's a slow climb -Getting demoted costs you a rank, usually dropping you to about 75LP on the rank below, about a 7--8 LP higher penalty than an average loss -getting demoted requites you to win 2 games to get back into promo games, then a minimum of 2 more to get promoted again

To summarize, going down a rank requires you to play (and win) 4-5 games to get back to where you were before the loss. This is assuming you have no more D/Cs and losses. This is a VERY HEFTY PENALTY. Being demoted should be a penalty for not playing well, not because someone else has bad internet or rage quits.

Party ques would of course nullify this to prevent abuse, and the person/people that D/C would still drop rank.
