Tonight we get our second Icecrown Wing and woot! am I ever excited about it!
On the eve of seeing some down and dirty plagues, I'll post my 4th Icecrown Boss review for DPS DKs.
Saurfang is the first 'real' gear check boss. Your guild may have had a little trouble with Lady Deathwhisper, but if you got her, I'm sure you're past the Gunship and on to Saurfang! You need to get him dead before you can go back inside the Citadel, so let's get to it! There are some strict dps requirements to get him down, so do your part and soon enough you'll be running from slimes. :)
Saurfang is for the most part a tank and spank fight, so let's get to it!
Pull/Phase One: You should be up on the pedestal getting ready.
If you summon your army of the dead while Saur is monologuing, then they'll be down before the first blood beasts are summoned. Why is this important? Because if you aggro the beasts, they'll stay on the pedestal and melee you, giving Saurfang waaaaay too many marks too quickly.
You should be unholy for this fight. How often do I give you a specific spec? Trust me on this. But if not, let me elaborate. The only reason you can legitimately give to NOT be unholy is if you a) already have an unholy DK and b) your raid desperately needs the buffs from another tree. Otherwise, unholy it is because 1) the casters need to kill the blood beasts asap. You can pestilence diseases to them all, applying the 13% debuff simultaneously. Just wait to do so until the beasts are already leaving the pedestal to ensure you don't get agro. 2) the other reason you should be unholy is you don't have any primary attacks that are aoe. Blood's heart strike will hit the beasts and frost's howling blast will do the same so you'll have to either gimp your dps or risk pulling the beasts to you, neither of which are acceptable.
So, for this fight you should simply dps your merry heart out. blow your cooldowns. Save your haste potion, but use all your cds. When Saurfang is at about 15-20%, your raid will probably blow heroism/bloodlust, and your gargoyle should be back up. Hit potion of speed, gargoyle, and go to town. This being a tank and spank, your rotation should be simple. There are no other special dps tricks that I'm aware of, except to anti-magic shield when you get blood nova.
The only other points to remember are: pestilence when blood beasts are leaving the pedestal and chains of ice a blood beast if asked to do so.
Phase Two: There is no spoon. Just dps. The fight consists of dpsing and more dpsing, and being careful to not pull blood beasts.
DPS for DKs should be very good on this fight. There aren't any major dps buffs like on Twins or aoe craziness like on Onyxia or Faction Champs, but you get to sit there and smack the boss. DPS DKs should fare very well and compete with all other classes for second place behind any decent mut rogues.
