Everyone on this server has a line.. lets say hypothetically tomorrow they introduced LFR level gear on the store.. then would you have a problem with it.. From what im seeing a lot of people's line is at stats on gear.
And it might never happen, but if it did, if it did, would you be okay with it? just because your line is at stats, doesn't make other's whose line is at moggible gear somehow lesser people than you, or wrong. That is what they want to fight against.
in the hypothetical world, if there was stat gear, you wouldn't be able to fight that either, because blizzard is a company and you can always do normal or heroic modes for better gear.
