Wait...wouldn't it be the other way around? Online gamers HAVE to play with the default rosters that are sent with the game. Yea, they can edit the names of players, but that's the only thing they can edit that will show up online (things like changing skin color, positions, ratings, class, etc. won't). Where as offline gamers can edit the rosters to their liking so they can start their Dynasty with THEIR rosters, no matter what changes they make.
