How it should have worked and maybe could through updates,
- Progression system with ranks that unlock every single Halo Reach armor through gameplay only.
-Mk 7 default armor but requires battlepass/store to unlock more pieces and attachments.
-The store contains coatings, new armor attachments stupid and normal stuff, armor effects, emblems, vehicle stuff, and brand new armor sets.
Now of course this may not happen ever or before more armor pieces are bought, so either customers accept that they chose unpressured to pay for cosmetics or they get some sort of credit refund.
