What is the best spec for tanking?
There is no real “tank” spec for a DK. All three talent trees were designed to be able to tank or DPS. What I look for in a DK tank when I’m not playing Sharvhan is 5/5 Blade Barrier from Blood, 5/5 Toughness from Frost, and 5/5 Anticipation in Unholy then points in any tree (that’s not completely boneheaded) and decent tank gear. Once you have those three talents maxed, you’re golden. The rest is simply up to your personal play style. I enjoy the AE aspect and Frost abilities, so that’s the reason why I chose Frost. Self healing of Blood didn’t appeal to me, and I already have a hunter for a pet class, so I didn’t go Unholy.
