From armor to weapons, there's a wide assortment of gear already datamined by the folks at MMO-Champion and I have to say some of this stuff is astonishing. We've talked about gear resets before when previous expansions come out, but when you're looking at such a massive DPS increase between an epic weapon dropped by the heroic Lich King and the crafted weapon you can equip at level 81, it seems like this expansion is really serious about it. Just one example is this level 80 blue tanking hat with 290 stamina on it, a clear sign of the increase in health pools we were told we'd be seeing. The new design paradigm of Cataclysm is definitely showing up in these items. It's safe to say that if you haven't been raiding, you'll probably catch up quickly, and even if you have you'll be replacing items pretty early on.
