In the absence of good data, you don't use shitty data, you say, "I don't know".
Also, we could harp on this shit all day long and it doesn't matter one fucking bit. Blizzard bases very little of their changes on what people bitch about. They do pay attention to complaints, but it has very little weight vs their real data.
So it all comes down to... Blizzard will do what they see fit from their data and we can't do jack shit about it.
EDIT: So you guys can piss and moan about anything you want. I'm going to go enjoy WoW and what comes... comes.
