Hi all,
So I have played GD for ages, but have always just copied builds and not really paid any attention to how the mechanics work etc. I have come to a point where I am fed up with doing that and want to start making my own builds. Not bothered about complete min/max but would like to be able to do Ultimate I guess? You have probably heard this a million times heh, I am aware that a certain amount of my own trial and error is needed. 
Having watched a couple of videos on Youtube and reading a little, I think I have gained the confidence to attempt something.
Please could someone look over what I have decided so far? I think the skills are ok, but the devotions are not right. My theory is Death knight focusing on Vitality and Health regen/steal on attacks. I’m not sure on Cadence point in there but felt I needed somthing while I wait for the Bone Harvest cooldown. Gear wise I am under the impression there isn’t anything dedicated to Death Knight so will wing that and have omitted anything from the grimtool.
Disclaimer: I know this is probably awful, feel free to laugh 
But I think someone telling me the massive mistakes I have made will help.

Genuine thanks in advance!
