I've been playing for the past 2 weeks (about 60 hrs) 160hrs in total and not one cosmetic item, weapon skin or gear dye has dropped. I must have opened hundreds of backpack/ luggage. Before you all say "just rng" it's not. Since entering world tier 4 I have had none. People I have been playing with are getting plenty.
Believe it or not, I'm pretty sure the 40 or so clothing items and 10 skins are all that is in the game right now, which is kind of shocking.
I reported the same issue a few days after launch, and after comparing notes with others having this issue, we all had the exact same items...
Pretty disappointing, eh?
I am also having this same issue. Ever since I reached level 30 I have not had any cosmetic drop for me. Before 30, I was getting several cosmetics within a few hours gaming. It's been a couple weeks since then. Just yesterday I ran with a friend who seems to get about 3-4 cosmetics during around a 3 hour session of mainly doing missions, not even really running around open world intentionally opening the luggage loot bags.
