Death Knights and their Single Target DPS
So I'm pretty new to DKs I'd say, although I've been playing wow for 7 years or so, mostly vanilla/mop.
Started playing here recently, and went with frost DK as DPS.
What I've noticed is that they do HUGE AoE damage since I was able to crit 90k with Howling Blast in ICC rep farms with just 4.9k GS.
Although, I've been wondering if Unholy or Blood is better on Single Target DPS such as Boss Fights.
Would like to hear more proffessional thoughts and oppinions and tips, how and what should I do/build.
Cheers.
