Kind of funny but the product ECNL provides isn't a big secret. Regarding your pic DA is gone and E64 is a dead man walking so I'm not sure how much they apply.
What recently happened is that GA and DPL are now officially both nationwide leagues that work together. What you'll start to see is that most GA clubs will place their 1st teams in GA, 2nd teams in DPL, and 3rd teams in XYZ local leagues.
The setup basically mirrors ECNL/RL but has minor advantages. The first being that a club doesn't need to be GA to play in DPL. The second is that GA and DPL are separate leagues, this brings more scouts (than something like ECRL) to events because there might be top teams that aren't GA playing.
How is more choice ever a bad thing?
What I find ironic about the whole ECNL vs GA debate was that after DA blew up ECNL could have brought all the DA teams into ECNL and had a single youth soccer league for all top clubs in the nation. Unfortunately ECNL chose to be petty + get back at the clubs that left for DA + make them beg to get back in. Taking things personally and looking for revenge instead of looking at the situation as an opportunity to expand the brand is what allowed GA to put its foot in the door. Now GA + DPL have grown to the point where it roughly mirrors ECNL + ECRL.
