I have noticed that the combat logging has skyrocketed. Usually, when you're in a gunfight and you win, whoever you faught doesn't die, but becomes unconscious. This is usually when they disconnect preventing you from looting their gear. Or, they just disconnect during or before the fight. A timer, similarly to mmo's like World of Warcrafts, would make combat logging much more difficult and in turn, make it more fair for other players to be rewarded for their fight, rather than losing ammo and become frustrated.
