If there's anything that surprised me the most out of Cataclysm, it's how fast you replace your gear. While Blizzard made it clear that you would be replacing your Wrath endgame purples with greens as early as the first few quests, I didn't quite expect to replace the Cataclysm blues I got with quest greens in the next zone. In the end, you'll only be wearing your new shinies for a few hours (depending on how fast you level) before replacing them, so looking for gear before level 85 will be somewhat pointless. You're supposed to dump your gear, so don't fall in love with it, even the blues. Especially the blues. The folks at Blizzard want you to graduate to purples. They've made it so easy that they made blues easy to replace.
So what do you have to look forward to in Cataclysm? Well, quite a bit. While this is supposed to be a gearing guide, anybody who's quested through the expansion knows that you pick up gear as you go along. On the other hand, it's going to be nice to know what to aim for once you hit the big eight-five. Hit the jump to start looking at purple shinies.
