Play. There is no situation aside from personal emergency or injury that you sould remove yourself from the game. You don't need to be firing your marker to make in impact on the game, you can still take objectives, draw fire, communicate, think. The most important tool in paintball is your ability to think and react to a situation. You can always still tell your team where people are, and can draw fire so they can work in a better position. In most rec games, you can easily sneak up behind someone and tag them, or offer surrender, you don't need paint to do this. And just maybe, youll find a sympathetic teamate to lend you a pod.
Most importantly, if you play paintball with the mindset that you can just walk off when you run out of paint/air, youll take that mindset to the rest of your game, you'll shy away from important objectives just because you don't think you can pull them off. Personally, I play with the never give up, never surrender mindset. I don't ever remove myself from the game, and I don't surrender when someone has a bead on me, part of it is you just never know, part of it is I'm not going to give anyone easy eliminations.
And I mean nothing personal by this, but a lot of good people have died horrible deaths as a result of your namesake. It is a disservice to our sport to relate his name to it.
