Because DKs weren't the only class without -any- form of raid utility.

[/sarcasm]

Seriously, what do DKs currently bring to the raid besides damage? No real raid buffs (only passive ones). No ressurections (excepting only the current form of Raise Ally, which is rarely useful). No Crowd-Control.

Seriously, DKs needed some utility.

They have utility. They bring the Agility/Str buff, 4%more physical/8% more magical, the ability to pull wriley mobs back to the tank via deathgrip, the BEST aoe kiting via chillbains and absolute zero (although they would have to spec in and out of it) and one of the best raid savers, Anti-magic zone (again, situational, but almost mandatory for fights like Nefarian) and to my knowledge one of if the only real tanking spec with raid buffs (both 10% attack power and minor raid healing through leeches).

Heck, even the old raise ally was, in my mind, far more usefull then this. In 10 mans you only get one battle res, but a dk can ghoul rez as often as he wants. Sure it's gimmicky, but after the brez is used that ghoul can be the difference to a 1% wipe and a boss down.

Not that I agree with captain QQ up there, but don't try and say you have zero raid utility when, if you're willing to spec into it, you have some of the best situational abilities in the game.

"and to my knowledge one of if the only real tanking spec with raid buffs (both 10% attack power and minor raid healing through leeches)."

Pallies, and druids (or even warriors, if you count shouts) aren't real tanks? I wish someone had told me that before I started queueing for all those heroics =(

@squig_masta AGi/strength buff comes from both warriors AND shamans now. Deathgrip, atleast the way you described it, is rarely ever used for that in raids. The only time I've ever needed to do that is in 25 man BoT trash up to the twin dragons. Speccing into chillblains is a significant DPS loss. I have yet to find any talent called "Absolute zero" even with multiple wowhead searches. Again, speccing into Anti Magic zone is another signifcant dps loss and is not found in any of the viable PvE specs. As for your view of Raise ally as it is, terrible. You can't use it whenever you want. It's on a massive 10 minute cooldown. other than that, it's horrible to use anyways. You literally would have to run around, looking for a dead body, click on it then res it, all for a minimal amount of dps that the ghoul does. They are changing Raise ally because it's terrible, and always has been terrible. Really everything you said was wrong, and I have to wonder if everybody that thumbed you up has even played a DK before.
