Given that the matcher can come up with bad matches on a regular basis when the population is low, perhaps it would be good to have a “circuit breaker” that stops the game and awards the win if one side gains a wide lead very, very quickly.
I have played more than 3500 matches, and when I see this happen, the winning team wins 99% of the time. Sure, I have seen comebacks, but rarely, and almost never when this common “pattern” appears.
And we all know that people give up and “stealth AFK” anyway when one team dominates. They don’t announce it and stand in base, but they effectively stop playing anyway to end the game fast.
