Are you sure? I know that's what was generally accepted in earlier stages of the DK's development, but I thought they decided to switch around the purposes of some of the talent trees with that last bombardment of WotLK news.

Lol, you're right. I was gonna say this too, but I read the post too late.

It is believed they build threat by dps. He's correct.

Mind referencing that claim? The frost presence is still the +armor% presence as far as I know, what makes you think it's not going to be the tanking tree as well?

Quoted from the WoW official DK site:

"Frost: Talents in this tree focus on tanking abilities. Frost Presence increases threat and lowers damage taken by a percentage."

While this is what is stated, having seen what they are offering as 'tanking talents' in the F&F alpha, I'm VERY skeptical on how a DK will tank. Yes, I understand that they generate threat through DPS. What I don't understand is how they can be considered a tank, much less the frost tree being considered the tanking tree, with one, count them, one physical damage mitigation talent. Even that talent is just an increase in armor, iirc. It's been said that a DK will not tank with a shield, but a 2-hand weapon. Needless to say, I'm worried about the standing of the DK's 'tank' status.

Well, the frost tree not being a 'good' tank tree is a different statement than saying that the frost tree is not 'the' tanking tree.

Death Knights are more for tanking casters, as I understand it, rather than physical melee attackers. A shield will do little good against a caster anyway. :)
