Multiplayer: Hit registration on multiplayer feels inconsistent and outright broken sometimes. My tracking and aim is solid, but I've noticed that every now and then, bullets just do not connect with your target. I've counted three instances when I've been in melee range of somebody, only to have my bullets phase through my target. This has happened twice at medium ranged fights. Worrying.
Elite Armor: All pieces of Elite shoulder armor clip through and stack on top of each other. Not a huge issue, but it is fairly off-putting.
Misc: Been awhile since season one started. With the influx of challenges rewarding seasonal points, perhaps it's time to add a few cosmetics to the seasonal challenge list. Nameplates, emblems, helmet effects, maybe even a new helmet for both species in multiplayer.
