Update

New Federation Roster and popularity system.
-New Fed Roster system that will automatically promote and demote rosters depending on the popularity of the shows.

The stars and popularity for the feds and for you is dependant on if you win or lose, and how well you did in a match. If you fought a pushover and won easily you wont gain as much popularity as if you fought a match against an even opponent.

So this means what exactly?

Same as always, only difference is there'll be no fights between the top two of the region to see who advances to the next level. Now the highest goes up and the lowest goes down.

At a guess.

And I think there's a change with the fans gained.If say Gerardo fights me,he will barely get any popularity.

Its always been like that so thats not changed, think they're just trying to stop people asking why their pop. decreases if they win in light-green and whatnot.
