Please lets not put the fault at the the players. Aside from there being such "good" feedback as defined by you which was ignored/not acted upon, it is not the players' job to tell Blizz how to fix this. If they can provide suggestions, cool. But if not, that doesn't make their feedback worthless. There is merit to listening to players saying "I don't like playing Blood because it feels so slow when we have to catch up to mobs" or whatever.
I mean look at stuff like the recent WotN nerf, Tombstone or March of the Damned. These talents are utter garbage in their current state and any feedback given to improve them has been ignored so far. Are you seriously going to say that this, too, is our fault? It is not even recent feedback, it has been mentioned a couple of weeks ago.
