Dont get me wrong, I think airsoft is fun but the competitive side is a joke IMO. Paintball is its own skillset whereas airsoft is many non-veterans trying to imitate military tactics. That just seems... goofy, for lack of a better word.
So what if it has a pro league. There are scenario tournaments at World Cup. Scenario paintball and scenario airsoft are practically the same thing only the projectiles are different. I don't play airsoft, but it is a sport if paintball is.
That logic is flawed, just because there is a genre of paintball not designed as a sport doesnt nullify the fact that there is one.
Woodsball and airsoft may share an aesthetic/theme and you shoot each other in both but that doesnt mean they play ANYTHING like each other.
