I hate ffa dm but i still do it. every session I get into, i end up with like +20 or 30 kills only as literally everytime, mroe than 70% of my deaths are either getting shot as soon as i spawn or from the back or from the side when I'm fighting someone already. It's somewhat annoying.
Sadly there is no better way.
Maybe arena servers but you get 1 fight every 30 seconds
