Suggestions for Comp gameplay:

-Que sound for Ready Checks.
-Report Player for suspected cheating/glitching/exploits.
-Add indication of your elo change in after match report.
-Change the objective indicators to fill and unfill(like a loading indicator) instead of flashing. This is confusing sometimes about what team is doing what.
-Kill cam for final kill of round.

This is all I've come up with after 10 hrs of comp play.
