People not calling out that they have been shot, can be very frustrating for everyone involved in the game. Even if you were not directly involved in a firefight, with someone who won't die. It can bring down the morale of the entire group. Making it less fun for others. I can understand some newbies may encounter issues when beginning, but if you get hit, say your hit!
I hate that when that happens.It dose at times make`s you want to quit playing at least with the cheeter.But all you can realy do is fire on them till you are boreid or dont want to wast any more amo,then walk away.Maybe if you agnore there hits and them they might get the hint.I dont know but it is one of the few of the negative`s of the game!!
