I think they were a qualifier to the worlds and basically got the same field, so why not call it the American 14.1 Championship and unilaterally claim that? I would... especially since Dragon Promotions unilaterally claimed the "world" title w/out a sanctioning body, since there was no competition for that event.
I always think better to have someone do that versus say "no event this year," so I'm OK with it. I think if I ran the very biggest qualifier/state championship in the country with a world-class field, I'd def rebrand it too.
