I dig it. Sometimes I know a team's going to be toxic from the get-go, and I don't want the temptation to say something snarky in the process of getting to lane. Not to mention sometimes I hit the wrong teammates while playing with duos, and that (ONCE UPON A TIME, anyway.) means that they get de-listed as a friend.

A small note, I may be thinking of a different game that counted an ignore as a de-friend, I haven't done much duoing lately.

UPVOTE MY STUFF!
