Seriously we can only see what they want us the craft/ buy. There could be like 100 skins made right now that we will only be able to see in the shop. Why are they hiding the good stuff from us? If we don’t have it or cant craft it, we should at the very least be able to see it.
Probably to maintain interest in the game on a week-by-week basis by releasing stuff in small trickles. GOW4 was like that with an average of 2-3 new Gear Packs per month (during 2017 anyway).
