i've said this before but erm, i think they need a bunch of more weapons and armor so they can put them in 3 different "caches", one you can only get through completing activities(raids, nightfall etc), one you can only get through crucible and its events, and one you can only get randomly through engrams and whatnot, these "caches" will have legendary and exotic weapons and gear, xur needs to stop selling exotic weapons, it will avoid things like the suros regime plague, also getting a weapon through an engram or completing an activity for later on to see it available through xur makes it feel cheap and less rewarding, gamer x investing so many hours and finally being "rewarded" with an exotic wakes up in the morning and sees that gamer z and a legion of others who haven't played the game not even for a third of the time or completed the activities he has have the same weapon/gear because its available through xur and they were lucky enough with the rare coins drops, that's bound to make you salty, "what's the point of all the hard work/hours? i'm just gonna wait for xur"
the light system needs addressing because it ends up making everyone looking the same because we all wear the same pieces, it wouldn't even be that hard to fix, all they is a wider variety of gear or a lazy fix would just be having more "powerful versions" of the gear pieces you had in the game up to level 20, add shaders, colors and you start seeing different looking high level guardians
the shopping system needs addressing, the 3 faction shops requiring crucible marks is bad design, at least one should require vanguard marks, and one glimmer, we can only use glimmer at the normal gunsmith and after you've gone past level 20 most of the stuff he sells, outside of ammo, is useless. You can also use glimmer at the outfit lady but the selection of emblems/shaders available through her is pretty poor which results in players regularly hitting the max glimmer cap because they have nowhere to spend it.
i hope they won't be patching every weapon the community complains about, granted no weapon should break the game but yeah, you need weapons/gear that people will strive for
i also want them to go crazy with designs, perks, gear, weapons and color patterns in the future, so much potential but so little of it being explored, so far this game wants you to do everything but "become legend", everyone looks the same(lol light system), has the same weapons(lol xur and lol limited choice) and they seem intent on making everybody play the same way
