If you're subbed you get like 1500 cartel coins "free" and 150 every month you continue to sub. What does it matter if you have to get it off the market? You're getting a return on your first year's investment.
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.
