Of course it is, its paintball mate.
So you if you got shot in the back of the neck, at point blank range, deliberatly, 50 times, and you were seriously injured, you would say "Oh well, thats a shame, it's just the risk I run playing paintball."
I doubt it.
I accept that playing paintball, we are going to get shot. Sometimes, we are going to get shot alot. But I don't think that means we want or deserve to be shot that often. My point is, our sport (like many others) carries risks. However, I think it's our duty as responsible ballers (and adults) to minimise the risk. One good way to do that is to stop shooting someone when they have been eliminated.
I accept that if I get mugged, I am likely to take a few hits. Thats fine. What I don't think is fine is a player putting a few into me, then registering that they have eliminated me, then putting a few more into me "to make sure I don't spin" / "to give me extra love" / whatever.
The problem is some players spinning on their mugger when they know full well they have been eliminated - I don't think the solution should be for us to punish every player by giving them extra love, it should be to crack down on the spinners (I have spun on muggers in the past, but I've never really thought about the long term implications until now).
I accept that maybe the hits bounce but lets be honest, if someone puts 3+ shots into your back/pack/head at mugging range there is virtually no chance that they all bounced and even if they did then they are likely to put more into you until you are eliminated.
I would rather get mugged by a few shots and walk. If very occasionally I found out later that they all bounced, well it would be a pisser, but overall it would be a better situation than getting drilled every single time I was mugged.
I think the point I am trying to make (somewhat long-windedly, I'll admit), is that I think it would make our sport better if some players treated their opposition with a little more respect.
As for deliberatly shooting someone in the head - I accept the reasons for it, however I just hope it doesn't end up with someone being seriously injured in a mug. I don't really want to be forced by the rules to wear full head protection when playing, but I can see it happening if there is an incident. Personally I would always go for the square of someones back, simply because I am a crap shot and that's the biggest target
