I've been playing for 2 days now and I shit you not I've got maybe 2 whole games where no one has left. I play with a partial squad so it's mostly the other team but it's not fun steam rolling the remaining players either way. I've even had a few games that had people drop before character select was over... Why don't you just cancel the match and go back to match making like Paladins?
Of all my complaints about this very fun and awesome game, being forced at least 7 rounds in a lopsided battle is my #1
