I knew you wouldn't be leaving.
Time wouldn't matter if the content were remaining the same, but it isn't. It is being severely nerfed. THAT is why it should be different.
And it isn't a waste, when easy modes are implemented (and they will be), those sets will have a different color. For obvious reasons.
They aren't going to implement a 3rd difficulty, again no need for it. Look we get it, you want to attempt to flex your e-peen, Content gets nerfed overtime whether it's from overgearing it, or literally nerfing it, changing the gear from said content, even if just the color, is not needed, wanted, or necessary. Now get off that high horse that doesn't belong to you, and stop giving real raiders a bad name with that elitist attitude.
You're a fool if you think they wouldn't try adding a third difficulty.
You're like those people who told me they'd never allow PvE to PvP transfers. Or faction changes. Or any of the other features that they have added.
