Even if the value for money went down (which it prolly did), in the past I had to buy the hole pack while I usually wanted one. Now I can buy just the skin I want.
If I ever will in the future, I haven't bought much after they gave away the black friday pack 3 years back.
Anyway, its ultimately value for vs actual costs. Take your pick.
Well what you're being asked to do now, is hand over your cash, for a fake currency. With that currency you can buy the paint kits or whatever. Or just keep it. Frontier don't mind... They have your cash you have funny money.
But.. At the end of the day... You earned your cash, it's your decision how you spend it or give it to.
