Oh I read it. You did not... or rather, you didn't understand. You see... there's ranked 5's - where you can go in solo, duo, or other number. So your first response suggests you mean in SOLO/DUO queue ranked... which you never specified.
But even assuming this... it is still 100% possible for what I suggested can happen. And I've seen it first hand (minus the kicking player from game part) to myself and to others. One guy doesn't like how you are playing... well he ganked for lane x while you haven't been able to gank because you're constantly being 2 man or 3 man ganked yourself. And so when that guy decides you're trash and a terrible teammate, lane x supports that guy... even though that guy is throwing the game for your team by making terrible decisions.
Or... laner or jungler is having a rough time early on due to losing a 1v1 or 2v2 once and they being spam focused by the enemy team. They're not playing poorly and are setting it up for their team to help them, but their team doesn't. And so a jungler falls impossibly behind because they can't farm or they get 3v1'd in their own jg while their laners do nothing to help. And they can't gank because they'll end up 3v3 vs 3 fed enemies that they didn't feed... trying to make something happen for their teammates who fed hard in early lane w/o ever being ganked. Which means they lose the 3v3 or even if it were a 3v2, they'd still lose. And so team blames "useless, selfish, afk farming jg". Even though the fault was much more on the laners.
The reverse can also be true; laner and jg...
And so because the jg that's throwing the game ganks successfully 1 time and feeds on the other 9 times ganking for a lane, the lane supports jg and decides that a teammate of theirs who is holding their own despite being 2 man camped all laning phase is in need of report because... they aren't ganking another lane enough to help and they don't teleport down to 4v5 contest dragon vs a fed enemy team or something like that. Like... sorry but not teleporting to suicide 4v5 and feed the enemy 4 kills plus dragon... but instead snag a tower and some xp/cs seems like a much better call than further snowballing the other team. But with your suggestion... said player gets kicked because their team is too tilted or noob to realize he/she made the correct call and it's the jg that's wrong for trying to force a 3v5/4v5 (if person tp'd) vs a team they can't even beat 5v4 right now due to how badly people did in lane. Seems to me like that's not a cool idea. And it is 100% possible even in solo/duo queue ranked as I've just explained. So... yeah I DID read your post. Perhaps with the more highly detailed explanation I've given now, you understand what I was saying better and see the massive problem with your idea.
I can see where it would be useful sometimes, but it also has great abuse potential like I just explained. Thus, I am not in favor of such an idea being enacted. And it looks like others are not either. It's nothing against you. It's merely seeing how the idea has too much potential for negative abuse.
