everyone bitches when their team feeds

everyone bitches when their team feeds but you never see any posts like "omfg I went 0/9/2 as top i didnt deserve this win i was carried by the 20/1 vayne please riot remove lp" and statically thats more likly to happen since the are 4 other possible people to carry when your feeding. So can we finally get rid of these "OMFG rank system so unfair look at this one isolated game where i went 18/3 but lost due to team" unless your gonna start bitching about all the games you unfairly won as well?
