All historical logs dating back to VoA in wotlk are available on worldoflogs, you have to go back a fair bit to get logs that were from the actual expansion though
They show what I've stated previously, the specs I've mentioned being strongest while also retaining a high skill cap. The evidence is there should you choose to read it
Firelands logs for example:

Siege of orgrimmar, ignoring the stupid vengeance stacking logs you can see that afflock unequivocally the top dog and as you go down in rankings enhancement shamans, bm hunters and mages start popping up.

Evidence is there, I've given you a start. Up to you whether or not you analyse and accept the facts or continue with your fairytale
