Yes, the Premiership and Super Rugby are the next things I want to fix.
The goal is a mod that is both accurate and stable.
At the moment, I've been sidetracked with trying to decrypt the motion capture animations from the game.
I want to mod them to de-power the dive tackle, change the box kicks to an up & under type motion, remove the lineout throw 'arm flinch', etc..etc.
Maybe even add a few new ones, such as corner dives, different offloads, tackles, high kick contests..
