Advancing Through a Sea of Toxic Sludge

Is it just me or is it practically impossible to rank up with any sort of consistency? I am currently 237 games into ranked and I just got up to bronze 2 all the way from bronze 5. I have played 2 games since getting into bronze 2 and have lost both games, horribly, due to poor sportmanship or people just saying F* you I'm going here whether you like it or not. In the first game we had a guy refusing to communicate, coupled with the most toxic ADC it's ever been my misfortune to play with. In the second we had a guy who decided a solo top vayne was a better Idea than playing an actual top champ, and when we begged him to go bot he refused.

So now I'm 2 losses in bronze 2 and am terrified of losing again and getting sent back to 3 all because the community of bronze is full of toxic, hateful, unsportsmanlike players. Can anyone come up with some sort of solution for this? Because frankly it's just plain unfair to those of us who are decent helpful players just trying to rank up and have fun. Honestly it made me stop playing league for a while when I got sent down to bronze 5 because of leavers and AFK's. So my challenge to the developers and even more so the community, is to find a solution to the toxic players pulling the helpful players down into the depths of bronze 5 with them.

Maybe instead of immediately determining the Lp at the score screen, it could wait until you close out, so you can report/honor the appropriate people. Then make the LP take those into consideration, so if you get reported you lose more LP, and if honored you lose less. Or if the whole team reports one player then it would "shield" them from dropping into lower ranks just because one person was being a jerk.
