The complaint I have is that artifacts and ghosts are way harder to get. There should be an accessory engrams or something that has ghosts and artifacts or just add them to the class item pool. I know artifacts can drop from legendary engrams but what about the ghost there should be alternatives to get ghost shells.
Edit: thanks Cozmo and I do know you can get ghost from factions which help yes but getting them in packages are a chance its not guaranteed. So if you open 3-5 factions packages and still no ghosts it tends to lead to a tedious and longer grind than needed.
Also with artifacts like the ghosts they are not guaranteed and have less opportunities to actually drop.
Artifacts are easy to get just requires some luck. Skeleton chest at end of golgoroth strike gave me 2 and 1 at end of cabal brothers. I have a 385 because of that
