In regards to headshots on Saturday in some games i was forced to take headshots to people in the British base, particulalrly int he trenches. i counted in one match a total of around 3 people whom were in the trenches who had to be dispatched only through headshot. I think people should realize that there are certain ares where they should take caution when occupying. As for your case Sanddragon, s hit happens, its part of the game, but I agree that there should be some safety precautions on player's parts. Be it facemask, half masks, or balaclavas, or just precaution when rubbernecking over cover.
On a related note, there should be limits on players on full auto bursts. Me, I mostly play on semi automatic, partly for realism but also partly because it gives me complete control on what im gonna hit and once I see a hit i can cease fire relatively quickly. Some games should be played semi only except for certain players (e.g. support gunners). The reason i propose this is because many people cannot hear a player on the recieving end of the burst saying hit over the noise of the motor and internals of a gun. So some people just wail on a player (its happened to me and teammates) until they see a rapid and usually angry response from the polka dotted player.
Not that I'm trying to limit players and their use of their guns, these are just propositions and suggestions. the moment you buy an airsoft gun, or any projectile launching tool, you should know full well the risks of improper use and other's use.
