This is a big reason we need some type of player grades/ profile. Allow us to see if their teammates and/or the game grades them very low for their play/ positioning. I would also prefer to have some type of training camp to play through before you can play online.. it would keep players from just joining without having any clue/ players creating new profiles to troll. Force players to repeat a section if they get a bad enough grade (or they have a big warning over their profile while in a lobby) I always want to try to find new players in drops but after playing with even a single troll, I'm usually done for the night. Even if they're on the other team it sucks, there needs to be SOME type of punishment.
Personally I just don't think drops should even have a rank though.. it promotes clubs to smurf and beat unorganized groups, and groups that are being forced to play with trolls. I think we should be pushing more teams to play in clubs, this would also speed up matchmaking. Drops should be played to find people to play with and to find clubs.
