It’s far enough into the game it shouldn’t be that hard to separate the customization options into parts like shoulder, chest, etc…
I agree with you, only being able to change the 2 separate sections are not enough, need some variety (specifically like in reach)
it will be fine see this customization in halo 5 is not here

Yes… Even something simple as halo 4 customization is still great. I want to make a more modern look of the wrath set by just sticking on the noble chest armor and forearms.
Wont happen because they have to adjust everything to make sure there is no clipping between chest pieces and shoulders its a lot more work then what people realize. Yss I would rather have the customization that we had in Reach and H4 but it simply isnt going to happen in H5.
