exactly. If there was no fear of pain, it would make the whole game different. You wouldnt be bothered about getting shot, so there would be no adrenalin, it makes the whole thing more real.One of the things I love about paintball is the adrenaline and fear. I know its likely to hurt if I get hit, but thats what I like.
If I was able to walk into a game with a full head mask and protective gear it would take the fun out of it.
