I don't remember HoR being a particularly difficult dungeon, unless you're comparing it to other LK dungeons. If anything, the mechanics in that dungeon were BC 101. It was probably such a shock to people because they actually had to whip out their CCs again. All things considered, that place was a blast; nothing special, but a breath of fresh air. I've personally never raided vanilla, but I don't think anybody wants the itemization to turn out anything like that. I think a lot of people see BC as the one that "did it right" when it comes to loot (with a few exceptions), but I could be wrong. If Wildstar loot rarity turns out to be similar to BC, I'll be happy.
