You need to implement some way to reduce combat logging, to many times have I been engaged with squads to have someone I'm shooting at combat log and then log right back in behind my position. Literally spawning right behind me. The last thing I see if their rifle muzzle materialize out of the either before I'm red screened. I think a significant delay before logging back into a server voluntarily left is gravely needed with the exception of connection loss. Just some input from a severely frustrated gamer.
