I don't think it's very helpful to be showing average kills and gpm for each player on the main stream. These are mostly meaningless in the wider scheme of things and give a very diluted impression of what Dota is about. You could have 350gpm and be the best player in a game if everyone else was around 250gpm. It's not a good stat. Kills is irrelevent for non-carries and also completely match/matchup dependent.

Fight participation (kills+assists as % of team kills) is a better stat than kills.
XPM would be a more useful statistic for all hero roles.

Also for the info popups, I appreciate the average KDA, but the decimals make it kind of hard to parse on screen (maybe just round it to 1 sf).
