Relic get's data the same way the dude in the OP did. Blind reporting on win rates without focusing on a particular skill bracket or organization of players.
You really went over yourself with the bullshit here.
On games I work I can get data on absolutely EVERYTHING effortlessly, player stats, gear, levels, currencies they have etc etc.
And you think relic doesn't have a simple data on win loss ratios for all factions in different brackets?
Are you that stupid when it comes to game design and data tracking?
