No its the massive amount of flawed systems that overshadows the little good this expansion did. Read your own post again. You couldnt name a single good thing that has no BUT following it. The initial release was good but not THAT good. The troll patch was a bad joke after the long wait. Firelands was a bland instance with few good fights. Then was Dragon Soul which is pretty much the pinnacle of everything bad you can do in a raid. Rehashed Environments ? Check. Portals? Check. Generic Nobody Bosses? Check. Rehashed Models? Check. Keeping it up for a year? Check.
Cataclysm started off average and ended the most terrible way possible.
