They're all trying to get signups to see which league is better. Give it time and most of the community will find the right league is best. Offers from NACL and beyond are just telling us what can be done.
Whichever Invite picks should be the one all of us go to, but until then we can't say for certain RGL or NACL will be the true definite NATF2 competitive league.
Furthermore, all the leagues have come up with great ideas, great websites, and maybe okay timing. With the continuation of TF2 Competitive in these leagues, there's nothing more than just finding the right area to which we can put on cruise control and surf as if it was ESEA.
I believe all leagues are a starting point, no matter how late they are and no matter how bad they seem.
