Is it possible to display the ELO for members in your PvP matches for the match mode? It will help us see who we are up against when playing. It's an open API and many sites show it so it shouldn't be a new thing for the game IMHO.

Or you could use the websites like normal people do. How much lazier can people really get lol. Its like one of the stupidest simple things, go on safari or whatever your browser is, type in url, then gamertag, boom. Everything you need to know right in your mug.
