We need a bullet style format. Quick as possible. Punishment for taking too long to do turns, pair them with other players that excessive amounts of time. Match making based on quickness, or rewards for quickness.
Roping or timing out has become a tactic to make the opponent quit, playing annoying decks like mono black or blue to "control" while taking excessive amounts of time with the only goal is to make the opponent quit. It's terrible for the casual player and it almost makes me not want to play when I take less than 10 seconds to do a turn and then the opponent takes 5 plus mins with some endless play of cards, it's just not something the casual player wants to deal with. Put those players against players that do the same conduct.
Bullet format, fast as possible like chess. You can see fb posts about this topic as it's a serious problem.
