Playing with promotional skins checked disturb the balance.
On the other hand these are unique visual assets (with the exception of the Priest “helmet“ which is a functional asset).
My wish is:
Move promotional skins from a starting option to a Marketplace item (armor and/or weapons separate).
I suggest a slight premium price compared to the manufacturing price (because these assets are instantly available).
Bonus: IMHO this would make recruiting Phoenix soldiers more viable (because my Fabs are busy with more important things than armors or weapons).
