Gotta agree as well. Everything that I thought was getting nerfed into the ground doesnt seem to be the case. Before the patch, I've been running a 1x DK Tank, 1x Holy Paladin and 3x Shamen. After the patch, I spent the day respecing, adding new glyphs, buying new gear (thank you, Justice Points!), and doing new gems/enchants. Once all was said and done, I made some new macros and did some Heroics.

Threat: Was never an issue. In the 3 or 4 Heroics I did, I had my shamen pull threat maybe twice, and the mobs were easily picked back up by the tank.

Mana Regen: The Holy Paladin never went below 90% mana. Shamen never went below 60-ish.

Love the fact that they combined the Paladin Blessings and Resistance Aura and the combined Shaman resistance totem!

This is giving me very high hopes for Cataclysm!
