Timed bans for people that quit early

I’m sorry to say this but there needs to be a penalty of some kind for people that quit Horde or Escape early. Played for over 3 hours today and only 1 game where people stuck around. Everyone quit before the 10th wave on every other game I’ve been in. I’m sick of it. There is a penalty in ranked so there should be for Horde too. Wish I hadn’t done the survey I was sent till today. Could of put my issues in there but I had a good experience till today.
