3 other people on my team wanted to surrender. Riot chose to make a system that encourages this kind of behavior so when I want chest drops I will exploit it.
I still have some more drops to get so I'm also going to continue picking champions I hardly ever play and focus completely on maximizing my own score until I get those drops, then I can finally go back to actually playing the game how I want to (choosing champions I think will maximizing chances of winning, making decisions based on what I think will maximize chances of winning, refusing to surrender when I think we have decent odds of winning, etc.).
