Did you fix the Strella weapon xp bug on Xbox (and possibly other platforms)? I DMd you and have commented about it a few times. At most I earn 25 xp per game. Definitely not earning XP from kills or destroying killstreaks. /u/ashtonisvulcan_iw
This should be fixed, but you’ll only see the UI update your XP gained after the match in the front end of the multiplayer menu.
