starting Week 16, Champions must defend against someone in the top 10 of their respective title's rankings.

However, fighters still can't fight for a world title after a loss and if by some chance a Champion cannot defend against an opponent in their top 10 then I will allow a fighter ranked in the top 20 of the performance rankings to challenge for the title.

Mandatory defenses will still be enforced.

let me know if you have any questions.

Just to expand on this a bit.

The four World Sim bodies have now published their own respective top 10 rankings, they can be viewed here: (below the Commish rankings)

Each body will have slightly different variation in their rankings, but they must be obeyed their Champions.

Other than that, everything is pretty much the same.
