Paul, Paul, Paul...
Ya know, the assumption that paintball is a sport is a false one.
There, I said it.
It has alot of the trappings of a sport...athletic participants, TV Coverage(after a fashion), and even a couple of leagues...but unfortunately I submit to you that it is not a sport precisely because of what you've noted earlier...the lack of consistency of rules.
Granted, the basic game is the same...shoot all the other guys and hang the flag, but I believe you've lamented the fact many times that there's just no consistency of the rules.
Until such time as a non-political, non-biased governing body is set in place to govern every aspect of the game, regardless of whatever league is putting on events, then it isn't a sport.
The PSP and NPPL aren't going to re-merge, and everyone knows it. NXL may or may not survive the year. In all three instances, there are varied rules governing various aspects of each league's game, whether it concern hopper color or perhaps the allowance of enhanced modes...none of them are the same.
So what's that leave? At some point 2 of the three dominant leagues are going to go away, leaving one to dictate what the "sport" of paintball will be, through even then there will still be a need for a governing body that publishes and enforces the rules. I suppose it's possible for the various leagues all confederate to create and support a governing body, but I don't see that as a likely occurance.
That's just the US...I won't speak for Europe, as I'm not European.
I went off on a bit of a tangent, didn't I? I guess it's my overly elaborate way of avoiding Paul's argument. The fact is that Paul's a bit more intelligent than I am, and as such I'm incapable of elaborating the truth that shooting fast is a learned skill. I'll leave it to more competent wordsmiths than myself to make that argument.
