1. Only able to see Emblems in pre-game lobbies whereas before you used to be able to see:

Other players gamertags, which team they would be on, their current rank\service record & much more



2. Post game stats are very minimal and not very interesting to look at for example not being able to see the medals you achieved in the match you just played and overall!



3 . The menu lags or takes a long time to load certain things for example sometimes when I try to promote someone in my fireteam to leader the "boot" sign doesn't come up straight away so if I'm hovered over promote to leader and press A sometimes "boot" shows up replacing my option last second and kicks the player rather than promoting them.



There's many more frustrating ones but those are without a doubt the biggest problems for me with the UI.
