Let's review, shall we?
The alpha ends, and the Beta goes up. Invites are handed out first and foremost to active players, who log in and look at the new Arms rotation. These unpaid, volunteer, experienced testers then do exactly what they were asked, and agreed, to do: they posted feedback, and the feedback about the gameplay was overwhelmingly negative.
The Beta continued, and more class changed happened, and more testers got invited and involved. However, the core Arms gameplay, based on the feedback posted as agreed upon, got worse with such things as the uselessness of Mastery, the removal of both Heroic Strike and Ignite Weapon, MS being optional, the lvl 45 talent tier being useless, Ravager being the only lvl 100 talent, and that our damage was insanely high with such a high skill floor. It was around this time that Celestalon asked for a constructive discussion on the subject, then vanished without a trace for...well, he's still gone. But amongst other things, he points out how we, the Beta testers they invited to test the Beta, are at the pinnacle of gameplay and knowledge, and not represenattive of the population.
The Beta closed, the PTR opened, and with it a whole new batch of testers. Again, most of them posted openly and often about how Arms felt poor to them. Posts that Arms was bland and boring are widespread and upvoted, while posts about Arms being fun and interesting make a small minority and are immediately downvoted. Arms warriors remain the single most vocal spec in the game about how their no-synergy, no-skill class is boring and not fun, and the only response by Blizz is to increase the effect of Mastery just slightly enough to make MS useful again at level 100.
The 6.0 patch hits. All remaining Arms warriors have this spec dumped on them. The outcry renews on exactly the same topics that have been on the Beta forums since literally the day it opened. Yes, the testers were representative of the population after all. Blizz offers no response of any kind, other than to lower the damage of WW and Slam, which was predicted by just about everyone.
Then at both Q&A sessions at Blizzcon, the only known place a paying customer could even hope for a direct response on this, again, the single most vocal spec in the game about how badly their class plays and how unfun it is, and Blizz flat-out refuses to hear them. They blanket refuse any and all class-related questions, unless you're asking about Mana Gems or lying about being a warrior and demanding MS get nerfed.
Please circle the part where we are acting like children, and Blizzard is acting like a responsible company.
