My 2 cents to this

I decided to play the campaign again after a year or so.

Could we be getting dozens of the AMAZING assets of Ultramarines customization that the campaign is completely full of yet the game doesn’t allow you to access them at all? There are helmets, pauldrons, backpacks, chestplates, legs, vambraces, cloths….

Speaking of which - customization unrelated - I have reminded myself once again how much cooler the jump pack is in the campaign (and PvP).

One can dream.
