Make req packs....

Req packs should drop primary customization items before warzone items, honestly, I think we should get an option to get like a preferred thing we get out of it, like warzone items and customization thigns, because i do not play warzone most of the time, sorry for the spelling and grammar typing while in game

Nah

They did it to balance out what you get. If you get all the armor unlocks quickly there is nothing really to work towards.
That being said, Arena req packs should have a greater chance of dropping XP items and Armor customization stuff over Warzone req items.

Or, they could tie armor into other things instead of making the majority of it only available to unlock with REQ packs.
