Instant Feedback System Favors Large Pre-Mades

When are we going to see some change in the Instant Feedback System? As a player that primarily plays alone, I feel that the current system is too slanted toward larger pre-mades. If group of three toxic players queue up with one another, its difficult to see any real results in a system that relies entirely on volume of reports instead of the value. We now have the ability to share replays of "sick highlights" why can't we share actual video proof of our teammates Inting or sitting on base manipulating the leaverbuster by moving a bit every couple mins?

I just played a game with this problem. The support Ori moved her ball every minute or so on the fountain and let the enemy team win, but since she was a part of a large pre made, and the enemy team doesn't care obviously, then there are no actual consequences. She most likely only received the one report that I submitted. So why continue to play a game that doesn't even acknowledge these issues let alone implement a non-abusable system to combat them?
