[Icecrown] Blood vs Frost

Hi, I would like to know Cons and Pros about Tank AND DPS Blood/Frost DK. Can't really decide which spec to get and make it DPS or tank.

P.S. I have a Prot Warrior(tank) which I like, but wanna try DK.

both are good, it all depends how you like to play and what def cd's you like more,

This is not what I'm looking for, sorry.

pros:

cons:
that is not what you are looking for

Blood is still bugged atm i think, single target burst is still really high but falls off in fights that last longer than 2 mins.
Frost can burst, single target and aoe very well and is much better than blood atm.

DPS > Frost. Reason: More raid utility, aka 20% melee haste, better constant dmg and aoe burst (ignoring the fact that blood dk is bugged far more than frost and not worth considering at all atm).
Glyphs: Glyph of Disease, Obliterate, Frost Strike (all 3 are mandatory)
Spec u should use as Frost DPS, from my point of view: http://wotlk.openwow.com/talent#jcZG0jxAMczf0cuzAofM0hx

Tank > Blood. Reason: More Cooldowns, more selfheals, overall more survability. Some might say Frost makes more aggro, but if u spec it right u wont ever lose aggro as blood tank. And all u need to do is cap spellhitcap (17% hit raid buffed) u dont need expertise.
Glyphs: Glyph of Disease (mandatory), 2 optional glyphs, u can use Glyph of Rune Tap and Vampiric Blood for better selfhealing and higher uptime on ur def cd.
Spec u should use as Blood Tank, from my point of view: http://wotlk.openwow.com/talent#j0Er...obsZhxbxVMZcbz

Blood tank definitely better. Blood DPS is useless unless you're BIS and/or armor penetration capped. Frost DPS better because of blood's bugs anyway
