I read somewhere PU doesn't want to nerf the circles (obviously take that with a grain of salt), but I do agree that it's overdone right now. I get that the current amount of late game damage is to prevent people in the final rounds from just tanking it for as long as possible with healing items while picking off people running in, but the time between shrinks in the last few rounds is way too little and the circle itself moves too fast. You might not even bother having a timer for the last one or two circles since by the time you get inside the next one will already be marked and you'll have to move now to get in. If you got hurt on the way in, then there's practically zero time at all to heal and still make it to the next circle before the blue catches you, and that's assuming you got lucky enough to find cover. It rewards campers who made it to the right spot way too much since everyone else has to constantly be running as fast as possible; and if it's on the opposite side from you? RIP unless Jesus smiles on you.
I've heard some good suggestions (have the circle always be slowly shrinking, tie the appearance of the next circle to the current player count, have the circle the same until the last two or three shrinks at which point it starts slowly shrinking).
