They could have just added a armor like this long ago, it is just greedy that they add a armor like this now on the cartel store and only in the darn cartel pack drops. Which means they may be very hard to get, who knows what kind of price they will go for on the marketplace, probably very high because of the demand.
That's baseless speculation.
They're a company. They need to make a profit, that isn't greed, that's business.
