Truth!!
I will freely admit that when it comes to the sup-air tournament scene I am pretty much an outsider looking in, but from what I have seen and from what I have heard from speaking to countless players, is that people are getting ****ed off with how serious the game is getting with little/no reward at the end, which is why a lot of people are coming back to the woods (FTW).
As for people/teams not being dedicated enough to train every weekend, I'll agree that a lot of people do have the "It's raining, to hell with this" attitude, but for most it's simply the time or, in the case of the younger unemployed players, the cost that is prohibitive. I myself would love to train every weekend, but overtime and traveling to see my girl stops that.
If I'm totally honest I believe that indoor Reball centers to be the answer. Weather is no longer an issue and obviously the reuseable balls end up cheaper than paint, meaning only a small "green fee" could be needed. However, as far as I know (I could be wrong) there are only two centres in the UK both of which are up north somewhere which doesn't help the majority of the playing populace.
I don't know if any of that makes sense, just my 2p worth
