WandumI would honestly not recommend only playing mge with one or two friends. Everyone strafes differently and eventually you'll just lock yourself into the muscle memory you have for how to hit your friend.
I've found out that only playing a couple of rounds at a time is subject to this problem, but if you're doing an extended session for about an hour or more then both players start adapting/learning and they will generally end up strafing differently after an extended amount of practice
