Stop rewarding people for playing like brainless monkeys
Players like this should not be able to reach Diamond.

I had this thing supporting me. It tried a ridiculous cheese at level 1 that had 0% chance of success and died. And then it kept trying to cheese, without any consideration for the minion wave or the location of the enemy jungler. It had absolutely no idea how to play intelligently; every time it got back to lane, it immediately tried to go all in, even when we were down 4 kills. It was indistinguishable from intentional feeding, and on top of that, it didn't even have basic game knowledge; they didn't know where to place wards, and they kept using all of their shield charges on caster minions.
Looking at this player's history, it's obvious that they always play like this. They have double digit deaths in every game, sometimes almost 1 death / 2 minutes. It's basically a brainless monkey, yet it still somehow manages to succeed like this, presumably by snowballing when the level 1 cheese succeeds.
This is totally fucking unacceptable. Decision making and strategic skill should be a requirement for winning games, not something that is optional.
