Dk groups took a huge nerf, and that really sucks for all dk groups. I dont run all 5 dks, my setup is 3 dks and one feral druid, but i've grown acustom to using a very solid frost heavy/blood subspec that works very well for single target AND HUGE aoe dps/ plus the side bonus of having an AOE CC that you can spam on rotation (works great for stopping casters and other fun stuff)

Here is a link to the blizz talent calculator for the spec i use :thumbsup:
http://www.wowarmory.com/talent-calc...00000000000000

the glyphs i use are Rune tap(for the aoe healing capability this is so awesome is not funny), Obliterate(thinking of changing this out to either howling blast or hungering cold when those become available on my server) and frost strike. Minor glyphs i use are horn of winter, raise dead, pestilence.

This spec takes full advantage of stacking frost buffs, good haste, and the Aoe is spectacular, if you're good at timing and such you can fire off some incredibly large aoe crits knocking stuff out quickly! Use runetap on a cast rotation*(3 dks, 2 dks) and you can get a pretty large group heal off every 15 seconds its amazing in instances

Basic rotation for bosses is: Icy touch, plague strike, blood strike*2, Obliterate, then spam frost strike for big dmg. This generates all your runes as death runes, so your next rotation will be 2 obliterates then icy touch and plague strike again, then spamming out frost strikes

For aoe packs, i like to lead with this rotation: icy touch, plague strike, pestilence, howling blast**hungering cold to stop everything in its tracks cc style and let your diseases tick for a couple seconds, blood boil 2 times, hungering cold again on another dk, howling blast should be up again so fire it off, then refresh diseases or spam frost strikes on whatever might still be alive. I use taurens, so you can put warstomp in the middle there somewhere to alternate cc as if you warstomp after spreading diseases, then howling blast, then hunger cold you can keep mobs cc'd for a long time lol


As i see it, this is the MOST effective boxing spec to use, it keeps major aoe and has solid single target dps(though nothing comparable to shaman dps lol) and the survivability can be unmatched with the aoe heal in runetap and the cc of hungering cold

good luck guys
