I mean so long as it works properly I can't see any reason to not add it to the server. 

It would be a small extra driving force to keep consistent players since there's no end to people wanting to know their stats and how they stack up on the leader boards. 

The XP rewards should resolve at the end of the round if possible though so it doesn't just show you off the bat that you killed a T as to echo on Hong's thoughts. 
Kind of like how score generally works where you'll keep the same value until the end of the round.
