I don't think I'll ever have Wrath nostalgia. Except maybe Ulduar. Heroics are already a joke, when I run them with my guild we pretty much chain pull the entire thing without CC. My paladin has been 85 for like, 3 days, and I'm almost 346 and can heal a chain pull of nearly any heroic, pug or not. The raids are challenging at first but after the first boss kills they become trivial. Thats normal. We spent more time on Twilight council then we did on HLK. Overall, I love Cataclysm. I hope future expansions follow its example.
