The Lax Nationals are a joke. It is run/overseen by the NLF. It was done to try to replace the UA AA games so they can control it.
Each Region is run by an NLF program. You can see it clearly on their website. I think the signups for tryouts in most regions were very low and why most tryouts were canceled. Several of the teams had 16-18 player rosters. That is SO low. Also multiple regions that were supposed to have teams were not able to field them. This also costs a lot more $$ for each than UA.
From what I have seen, the UA games and talent are much more competitive and independent (though UA is not perfect). |
