Ever wanted to RP multiple op/navi pairs? I know I have! :'D
The rules have been updated to allow the simultaneous RP of multiple navi/op teams. Note that you can only take advantage of this system AFTER reaching some important level milestones.
Consider this a test drive, however; if something starts to look wrong with this, the new system can be stripped cleanly from the rules. If something goes right, however, enjoy RPing multiple op/navi pairs. :V
