I personally don't care if people leave.
There is an option for a reason and as a solo queue artist, the amount of toxic players for "good people" are 3 to 1 in favor of the toxic players.
I am a great judge of character, I can spot a shitty teammate within the first 30 seconds of jumping out the ship/landing.
Especially in ranked. I died at the beginning of the match, the team grabbed my banner and both walked past two beacons with nobody in sight. I do nothing to piss teammates off because playing solo is rough enough trying to find a good team I'd rather everyone cooperate and get the best placement as possible. Its unfortunate they take 6 points if you leave from having toxic teammates. Would be better to give them time out that gets larger over time the more times you leave.
What's you reasons for caring or not caring?
