I have been having fun playing quad dk in bg and i am currently using a 2hander but not speced into obliterate! im using howling blast necrotic strike and frost strike

I am looking to start 5v5 and I have read (on these forums and others) that 2handers are better in arena for burst but dw is better sustained damage for bg

I tested out an obliterate spec on my main and had an increase of 3k dps on burst! this is obviously without resilience and im not sure how armor works on training dummies but im aware obliterates damage is negated by armor! and i wasnt using necrotic strike so I would think not specing into obliterate is more beneficial? but i may be wrong

I was hoping someone could give me a bit of advice. I have the ruthless 2handers and could upgrade to cata dw if it is better, but for the time being should I spec into and use obliterate or stick with the howling blast necrotic and frost strike? maybe using obliterate for burst on clothies? it just seems necrotic strikes debuff is far more superior!

Then when i can upgrade my weapons to cata should i stick with the 2hander or go dw?

Thanks
