I don't know why somone up there said that blood spec isn't good dps. I have two good dk bloods in my guild and they rape the dps charts. The better of the two is doing 7k+ dps. Maybe the blood spec you tried wasn't correct. Personally i'm a blood tank DW and I don't have a problem missing that much. I do 2.8K dps in naxx25 as a MT. currently my hit is only 200 as well. Another thing is to stack Strength not attack power with gems and such. The reason for this is because when you get buffs I.E. kings %10 to stats.....that's going to bump strength which in turn gives you more ap. As for agi you don't need to gem for that...just crit because your gear gives you the agil you need......raw crit is better then agil. Hope this has helped.
