Looks like the hardcore elitist of WoW got what they wanted.
They QQ that Blizzard nerfs content to cater to the "bads". Blizzard points out that the skill range of the player base is very large, that they can't make it too hard.
Solution? Different tiers of difficulty. Now that the "bads" are out of their normal/heroic mode, they QQ raiding is dying ...
