Is there any list with all the customizations and rarities?
Not looking for a youtube video that just skims through not yet unlocked armor/weapons.
In the collection area of the game I’m pretty sure it listed in order of rarity.
The best you can get currently is going into requisitions on this site and using the preview feature. It’s going to take a little while as people keep unlocking gear and such for screenshots of all the armors and helmets to become available.
