is there any doubt that you will win ascension and thus have a 6th slot?
the best teams on the continent will be in Los Angeles, and all NA teams, even those that aren't in the franchise, will train with the best teams
doesn't even compare with BR and LATAM that will have to train with what's left in the region
now, if even with this advantage, the NA team can't win the ascension, then you didn't deserve a slot anymore (which I think is very unlikely to happen)
