Honestly, while I get what you're saying I also don't think we'd have a good Homecoming if there was no Closed Beta where feedback and testing is actually focused.
Every time we go to open beta, non-testers (as in people who do not do a lick of testing at ALL) come out from the corners to rip apart any change they dislike. The Defense Changes is a primary example. People thought it was some game-wide super-change but actual testers pointed out otherwise. Yet they'd not hear the end of it. I'm pretty sure the Fly change was like that, or maybe I'm gaslighting myself into thinking it was. Also yes I know the opposite where staunch defenders ride or die for dev changes, but you can't get reactionaries without wild defenders.
At the very least, those (or they should at least by now) in Closed Beta understand better than the general populace that hard proof (aka testing and numbers) works way better for development than "This change is shit." or "This feels bad." because neither tells the why or the how. If we didn't have that without fail every Page/Issue? I could see validity in bringing the Gold Standard stuff to the forums. But I'm just a guy, maybe the devs/HC admins feel its already a good idea when they read this thread. Maybe its crossed their mind.
