But that's the problem. The players find the problems, explain exactly what they are and why, then Blizzard ignore them and go ahead with their plans regardless. Then everything the players pointed out comes to pass, and we get shitty mechanics and gameplay that drives people away. Eventually those people providing feedback are going to assume that Blizzard wants to make games this way, because what other explanation is there?
If they were still making high quality engaging games, they'd be in a position to say to players "trust us, we know what we're doing". But instead they have a track record of ignoring feedback that's later proven to be 100% right. You'd think at some point they'd realise they should be listening, but nothing we've seen so far suggests they've reached that point yet.
