Blizzard unveiled some previews of what the Cataclysm talent trees will look like based on some of the changes they’re making in the alpha test, and WoW.com has the scoop, including a wealth of analysis on the tree previews that have been released.

So far, Rogues have had their trees previewed, along with druids, shamans, and priests. Now Wow.com has had their columnists dissecting some of the specific trees and specs to reflect on what the trees may mean, so click through as the new columns are added. It’s pretty big news, and it’s a little unlike Blizzard to let news this major out unless we’re closer to a Cataclysm beta than we may have originally thought. Here’s hoping!

Blizzard has slowly but surely been releasing information about the updates they’re planning for the various character classes for Cataclysm, the upcoming expansion to World of Warcraft. They’ve already marched through most of their announcements, and a number of class communities are already up in arms about the proposed changes and re-balancing that Blizzard is planning to do with the new expansion hits.

It’s worth noting that these changes are still on the table and on the drawing board, and they’re by no means final yet. Also, there’s going to be a lot of changes and tweaks between now and Cataclysm, so there are more changes to come. Still, for those people freaking out and shouting that the sky is falling, I’d suggest you all calm down, relax, and familiarize yourself with the changes – especially since you should all know by now that Blizzard giveth and Blizzard taketh away. We just don’t know what Cataclysm is going to really look like; so there’s no point in trying to predict it.

At the same time though, there’s some great and juicy news in here, enough to whet your appetite and get you thinking about how your class might play when the expansion does land without jumping to conclusions, of course.
