BW's ingame collected stats show that Merc dps does more damage than other dps classes. That is the dominant factor that has driven 12 months of nerfs to the subclass. And throughout that process, the more BW nerfs Merc dps, the better Merc dps ingame collected stats look. Which is why the nerfs keep coming.
What Bioware does not comprehend is that player migration causes a inverse relationship between buffs and class performance. The more a class is buffed, the more new players/rerolls surge towards that class. The influx of undergeared, inexperienced players lowers that classes meta average productivity - which is what BW measures. Conversely, when a class is nerfed, the people who leave that class are the worst players using that class - as they are the ones who now find the class non-viable. The ones who remain are the best geared, most skilled players. Thus the meta average productivity for a nerfed class actually RISES.
We have seen this phenomenon in action multiple times. The 1.1 nerfs to Operative dps followed by BW's need to nerf them again in 1.2 is a prime example. In more recent times, the surge in Mara/Sent dps toward the Focus/Rage spec actually lowered that spec's meta average productivity. Which lead BW to buff them further. Conversely, as Mara/Sent players fled the Anni/Watchmen spec, those left were the higher productivity players. Which lead BW to nerf them, despite the widespread knowledge amongst the player base that they were the weakest Mara/Sent spec.
The bottom line is that player migration renders BW's ingame stat collection irrelevant. The ingame stat collection code should be removed and the server CPU cycles saved should be used to improve server performance.
Source? I hear you spout this all the time and it all sounds nice and reasonable, as all great conspiracy theories do, but I have no reason to believe it has any particular bearing on reality. Before the buff to Focus/Rage, Rage Juggs were known to be a strong spec when played right but weren't exactly super popular. Only the very dedicated played the spec, and they were good at it, which should have driven the spec's meta-average up, yet they were buffed (which is what led to all the FotMers). Whose not to say that the operative nerfs in 1.1 and 1.2, and the Grav Round nerf in 1.2, weren't all QQ oriented? People whined, they nerfed the whined about classes, and then they still whined later when operatives could still be dangerous.
Also your theory that BW primarily uses meta-averages still fails to explain why they Stockstrike knockback nerf, which appears to have been feedback driven, even if their take of that feedback was just plain silly.
As for your numbers stating that Merc/Commando does the most damage, I need some proof. Sounds like a stat you pulled out of your hind end.
Sorry dude, but without some hard proof that BW is relying totally, completely, and stupidly(i.e. taking numbers at face value instead of trying to interpret them properly) on ingame metrics, your entire theory, and by extension all your crazy rants on the subject, don't hold much water.
