Well that's just plain stupid. If you did that to me I would talk to the manager and hopefully get you kicked out. That's like saying even though barrel tagging is allowed at your field you'd get to butt hurt if you did get surrendered so you'd shoot the guy instead. Your logic is horrible.
So you would try and get me kicked out for not surrending to a person that is, in my eyes not a paintball player. Like I said, if you go into a woods scenario game with your Marker(be it a pistol, rifle, geo,ego, etek or whatever) and carry a foam Knife, sword or something else with you, and you tag me with me that foam item. Fine you win. But!
but, if that player starts the game with nothing but his foam sword, knife or whatever(note : Start) then in my eyes it is not a paintball player, but just another object on the field. Tagging me with your foam stuff, will in no way make me surrender if that is all your carrying from the very start of the game.
If that is screwed up logic in your eyes, fine. note though that I am just following the Basic rules of a paintball game. Which are quite simple, you shoot players, tag players with a paintball marker.
