The team sure has recognize a lot of problem pointed right in alpha beta. The whole "oh there are a lot of feedback" isn't properly addressing this issue too, because just because there might be different voices doesn't mean you don't change anything.
I don't think Blizzard is too stupid to do stuff; i think they don't care because the playerbase is so tolerant at this point that it actually makes very little sense to make changes. Honestly the only way to address this issue of complacency is to vote with your wallet, but I doubt that will happen since most players are as complacent as the devs themselves right now and the biggest dissent is maybe complaining on the forums or unsub for a cycle or two, which honestly aren't very effective ways to get the point across.
