I have said before that you need more camoed-out rec players in Europe. Your population density is sufficient, you just don't have as many players in your base. The way to get them, I think, is a strong rec scene.
We have American pro teams that can cherrypick because we have Am, Nov, and even Rookie team that cherrypick. Some of our Rookie squad guys play rec once every month or two and come back with recruits.
All respect to Russian Legion, Joy, Nexus, and the Ton Tons for the professionalism the adhere to. Those training schedules and attitudes are showing the way to the future. But as Munkeh said, American teams can adopt that approach, too. The performance of the Am and lower divisions is evidence that we are catching on.
This all suggests to me that you need to get the kids playing, and get all the kids playing. Paintball is a little like soccer in reverse, where talent pools and public interest are concerned. America has few kids who play soccer, Europe has many if not all. Rec is like sandlot baseball or playground basketball. Those guys are at least getting the basics in their heads. When one out of the thousands shines, you have effectively had a tryout with a thousand hopefuls, while eliminating the fluke factor a one day tryout has.
Don't be American soccer, Euros.
