PLEASE!!! OMG PLEASE fix the point system for ranked

Ill go ahead and get this out of the way, no i am not the best player on here i win and i lose... and if i lose ill admit that i lose pretty spectacularly :/

but what i cannot stand is getting demoted because someone on my team gives up and feeds the other team to hurry up and end the match, because "they're done with this round". i don't think i'm that bad, not the best, but definitely not bronze 4. all i'm asking for (don't know why i'm doing it no ones going to listen) is for there to be an individual portion to the point calculations. something that gives you the chance to negate at least a portion of the point loss for losing a match that may not have even been you're, or even you and 3 of your teammates fault. like i said i can accept a loss if i know everyone on my team was trying but i'm getting demoted because people get tired in the middle of a RANKED match and int... things like this should be strictly enforced... if people are trying to have a ranked match then inting and giving up should be punished, no i'm not suggesting banning there account from the game but at least make it so they cant play ranked, they still have norms they can do that crap in. for example, first offense 24 hour ranked ban second offense 72 hour ranked ban third offense 1 week ban and fourth offense ranked perma-ban. now i know stuff happens from time to time but say if these offenses are happening back to back then this is more than suitable. and go so far as to even make it so that after so long an offense will drop off like it was never there...
