Explain to me, how do you think their is going to be a leaderboard if they aren't going to show any player names? (Welp, looks like the Top 5 today is Fresh Meat, Fresh Meat, Fresh Meat, Fresh Meat, Fresh Meat.)
Because having a leaderboard isn't counter to names not being shown during a PvP match.

During the beta test a scoreboard was shown at the end of the match which includes people's names and servers. The names are simply not shown DURING THE MATCH to prevent trollish behavior.
