Idea: dynamically adjusting ring sizes
Ok so take a look at the screenshot: Round 1 (I emphasize it again: Round ONE) is closed in 1 minute. So it hasn't even fully closed - yet there's only 2 squads left: our team and one other enemy team.
I don't know if that's the case in every pub game but at least higher tier pub lobbies die that fast all the time and it's honestly just annoying to run around in a circle that is still huge while 2 teams run around maybe hundreds of meters away from each other until they eventually finally find each other.
The worst is when the other team is some camper team that has probably spent the whole game looting and now they're going nothing but running away and you have to chase them for 5 minutes or more. The game needs dynamically adjusting zones/rings (whatever they're called you know what I mean). So say round one is ending and ring closure is about to start but only 5 squads are left: the announcer then announces that the ring will skip to stage 3 or 4 or so to prevent a handfull of teams running around in a huge a$$ circle.
The advantage is: since it's dynamic it only happens when it is needed. Still 15 Squads left? Ring closes normally. Only 5 squads left at the beginning of ring 1 closure? Dynamically adjust it to instantly close to ring 3 or 4 size. Seems like a win win to me.
