So I love tanks, I have a Pally, Monk, DK, and DH tank (and leveling a Warrior as we speak).
My DH is my alt's alt (main the BrM and my main alt is my DK) so I haven't really had a chance to test them out yet.
The biggest buff I've noticed on ALL my tanks is the HP buff. Each one got about an extra 200k or so HP, which is nice. Guessing this is from the primary stat buffs that they did to compensate for the secondary stat nerfs. Two of my tanks have the Pryaz necklace, and noticed a buff there. (Pryaz only buff tanks hp by 15% where as other specs get a 25% buff, still a nice buff from before tho).
Any talent buffs/changes that are immediately noticeable to the VDH? I noticed that my BrM and BDK are doing more damage as well, is it noticeable on the VDH?
