50 games in a row, teammates drop solo

Why is it so difficult for players to stay together, drop together, fight together?????

I kept track of it every match, and just hit 50 consecutive games where at least one teammate dropped solo. This destroys the entire game, since it is literally designed as a 3v3 game.

It just doesn't make any sense, considering if players want to drop solo, they can just queue for matches solo, and have their fun without ruining the match for teammates that they don't want to play with.
