I was just watching one of MathChiefs videos for Spartan Ops. It seems to me that the ranking structure that was in well Reach and Halo 3 will be the rank system in Spartan Ops while this SR ranking system will be in War Games. While this isn’t confirmed, all the videos that have been released seem to point to it from the PAX build and the builds released after that. It still perks my interest but if this is the case then Spartan Ops may have a progression system while the War Games has the skill based system. That’s just my thoughts though.
