And before you look at a single graph you should look at the 2 years worth of data there that also includes the TR Realm. And yes some classes did have it "THAT BAD" Hunters didn't receive 10+ pvp oriented buffs because they were fine in the arenas. And just recently received 2 more in the latest patch.

Also bear in mind that Warlocks took the largest hit in population dropping to 7% of the overall population making it the lowest population class in the game.
If you also look warlocks may have been middle of the field (Average Representation) but they made it all way to 2400+ in ALL Brackets every season. Were some classes in some seasons never made it past 1900+ legitimately.
As i pointed out... Low population... Low Population = Low repsentation, is your repsentation disportionaly low? How many warlocks actively do arena and whats their repsentation in the look like? A Quick search of the fist Battle group i ran across looked like this.
There are warlocks making it to the top of the food chain, despite the massive numbers of DK and Pals in their way.

I never said that warlocks were fine in Wrath in fact I have agreed with the main point that warlocks need a little help. But I have also pointed out that some of the complaints and problems are self inflicted.
Till some of the issues with Burst and survivability get corrected across the board you cant really claim to be broken. The only classes that are doing well ATM have some kind of shield/invulnerability ability.
