Blizzard puts an immense amount of time and thought into every piece of tier gear (at least, you'd hope it does). For those of us who raid (even casually), it's the armor set we'll see our characters in the most. You get a blue drop out of a heroic, and you might replace it in a few weeks. You get a piece of tier gear, and ... well, the only thing that's prying that out of your hands is an even better piece of tier gear.
That said, our datamining friends over at MMO-Champion have released some terrific finds today -- the tier 11 sets for druids, rogues and warlocks that so many of you will be wearing just a few months after the Cataclysm release. The druid set, which seems to turn you into some manner of electrified bird-man, is absolutely gorgeous. Warlocks get a nice, evil-looking set that comes complete with skewed horns. As for rogues ... well, somewhere out there, there's a rogue who roleplays as an Arabian ghost -- and man, is he happy today!
Though the full warrior set is not yet in the Cataclysm beta files, MMO Champion did dig up the warrior tier 11 helm, so the Matt Rossi posse gets a sneak peek at its gear as an added bonus. The video for the druid tier 11 is above; rogues, warlocks and warriors will have to follow me after the break.
