Suggestion: Casual League
Basically a game mode that doesn't have penalties for dodging or leaving. Also if a player leaves they will be filled with a bot. Perhaps even some sort of accelerated game-play mechanic where most matches only last 10-20 minutes.
For those of us who have lives, bad internet, a needy job, or something else. Also as a new player WAY back when I first joined the no leaving rule seemed TBH completely clinically insane and was a huge turn off to the game. I have since sort of adapted a don't play if you don't have time view on the situation but I'm sure there are still people who feel the same way.
