Before introducing stat rolling, a reasonable custom party creation should be introduced first and foremost. It will be anything but great to want to create your party with the previous cumbersome multiplayer method

It can take ages to roll the right stats for just one character alone. Players of the predecessor versions know exactly what I mean... and I did not want this by four+ instances. Alternatively, a build saving with import / export function would be a workaround. Then you could build one character after the other and reload it when needed, which would be much faster and would'nt very taxing on your hardware...
