Wrong actually. It'll be better to spam IT then Howling blast.
Due to the change to the glyph, the new sigil, and various other factors, spamming IT twice with death runes is more effective then Howling blast.
Especially if you factor in that spamming IT can offer up more Rime procs so you can get a free howling blast so to speak.
In short, spam IT, not HB. I just need to find an addon that makes me aware when Freezing Fog (Rime) procs.
Anytime :P If only I could get some damn rep when *I* post things on this site.
EDIT: Also, you might want to add you should/could throw a DC between IT's, another effective thing to do.
It gives you that break in GCD to allow a chance for KM to proc before throwing out your new IT if you have the runic power.
Did what you suggested and picked up a 2nd Fang of Truth and dualed them last night in heroic occulus and using the same spells at the same time, my dps dropped to around 1700... huge loss compared to the slow mace in my main hand
from blizzard :
Howling Blast cooldown changed to 5 seconds
I believe the cooldown is 5 seconds now, so at least it should mesh a little better with 10 second rune cooldown.
We knew there was a risk in taking the Howling Blast cooldown off. Unfortunately, we saw dual-wield DK numbers as high as ever even with the Killing Machine and Gargoyle nerfs. It typically only happened when the DK was fighting multiple targets, which suggests Howling Blast is the right thing to change.
We still agree that a cooldown makes rotations more awkward, and we will continue to look for an implementation that lets Howling Blast be off a cooldown without all death knights feel like they need to DW Frost or go home.
(And no, we can't buff other DK specs and other classes to 7000 dps or whatever to compensate.) (Source)
Im only doing around 2k on bosses in 5 mans, any ideas or will this get better with gear? I just hit 80 but I have some crafted weapons and the spiked titansteel helm.
