Let me explain what their plan is. Also this is going to be a long explanation.
So 343 gave us 60 default colors in H5.
Fast forward to Halo Infinite and you get 10 of those colors for free.
Now notice how They made Armor Coatings Locked to specific Cores. Why? So they can sell you one of the remaining 50 default colors more than once.
My evidence: Scarlet wake, Scarlet Skies and Scarlet Empress are all the same Default red, ots the same shade of red you got free in H5. And they sold us that same red renamed in three separate bundles.
The game has 4 catigories mostyl,
Armor/Weapon/VEHICLES/ Nameplate Emblem.
So they took the restrictive methods of customization and took it further.
Emblems… Why sell you an emblem once when they can sell it to you 4 times to justify it as more content.
Evidence: The Current Yoroi 2000 credit bundle. States 5 items.
1 Armor affect.
1 Emblem( but the emblem appears 4 times locked to each Catigory stated above)
They made a very robust customization system and went and restricted players down to each individual thing.
They had no intention to make cross core customization because again they wanted a way to re sell you the duplicates items.
Why let you put that Reach Armor attachment on your MK7 when they can sell it to you in a bundle with 5 duplicated Emblems.
This was the plan to limit the items to 1 thing so they can re sell you the same coating. Imagine. Buying the same coating each week for one thing. One Weapon, 1 vehicle 1 Core.
Now take the 50 default colors and imagine how many times over they can do this just using those 50 default colors.
