Mercy mechanic for Ranked

Before I get shot down, let me say this: yes, there are some people who will be r%%%%%s anyways, but most people will empathize with the opposing team if they have an afker or troll, etc on their team. Also, the disadvantaged team will be less likely to complain and whine in all chat about their stupid teammate and be annoying, because nobody would want to give them mercy for doing that. Think about it. Mercy would give the same amount of lp to the winning team, and the losing team would still lose lp, except maybe a llittle less, and that loss would not be counted against them in a series. I believe most people would not abuse this system, I mean according to Riot, most people play to get a better ranking. There will always be those who are r%%%%%s/trolls who play to irritate others, and this would take care of that. Brings a whole new meaning to "beg for mercy"
