Something small that I think would make multiplayer much more complete would be better Victory screens and post-game stuff as listed below:
Once a match is complete, show the following during the Victory stance screen:
-Names/nameplates
-Top 3 medals earned
-Emphasize the MVP with a gold border around their nameplate
Post-match
-Add a post-game lobby of course (not gonna beat a dead horse here)
-Add a medal tracker similar to MCC that counts how many of each medal you’ve earned in PvP.
-Lifetime stats & K/D
These should all be relatively easy to implement, plus, there are so many new and whacky medals in this game that I think it would be awesome to show off the best ones earned during a match to keep players saying “you can do that??!” I believe these small features would keep the community more engaged, which is so important to keep this game going for years to come.
Here is a rough video example of what the Victory screen would look like with medals:
