So let's see... I think this is needed: "I TOLD YOU THIS WOULD HAPPEN!"
Now that that's out of the way, that's a stupid argument. People already see all content through LFR and Normal modes, Heroic modes are for elites. Isn't in the end that the reason they created these modes?
Well as I see it now it's not. Blizzard created these modes because they don't need to pump out that much content, they can have 8 bosses with 3 difficulties and nerf them over time, thus letting the people who are bad to raid normal after LFR, the normals and medium casuals in skill raid heroic and the elite and hardcore casuals... well they're done but they're about 5% so not so important. So this gives people a fake idea of progress, it makes them think that if they progress from LFR to normal and from normal to heroic they progress... but in truth, they do not because they get better, but rather because Blizzard nerfs content. So the skill of many of these people doesn't grow, but they push on beliving it does! This makes them remain subscribed under the impression they're as good as the elite raiders (something I saw in a recent poll as well where almost 2/3 of people who voted said they're as good as hardcore raiders, let me tell you this, most of you are not, and no, I'm not a heroic raider myself and don't want to and even if I did, the truth is I'm not skilled enough here, many of you are not either but you're made belive you are by nerfs).
Democracy is something that caters to all the people someway. When it only caters to a majority over the minority which is deprived of everything, it's called tyranny of majority.
