Seriously, think about how many things used to be public in this game and Riot has gone out of their way to hide them.
Enemies and allies ping
Load times into game
Your own K/D/A (actual numbers not just the K/D/A total)
Other peoples K/D/A
List of their champs played in client
When an enemy left the game
When an enemy got executed
Other peoples runes/masteries
Riot has gone out of their way to hide all of these things on the simple logic of "players will be mean to each other" Seriously what kind of logic is this? I think if a Rioter ever had to go into a MW2 lobby they would actually kill themselves. People typing shit to each other in a video game is not an issue, and anybody who thinks it is is not emotionally stable enough to be on the internet.
