The blood DK build is horrible, I just had to make a mmo account to make sure it gets addressed.
First off
Runic power mastery should never be taken, as a blood DK we will never stack are RP that high and if you do your not being quick enough with using your rune strikes.
Icy Reach would be fine if we were using diseases and actually having range issues but seeing as were not, don't bother wasting 2 points on it.
Lichborne, its a good cool down no doubt but your giving up a lot of viability just to get it, its not worth the sacrifice.
Abominations Might, its good for raids with that 10% AP buff, but next to every class will have that buff and they do not stack with each other! The str is next to none existent and just not worth those 2 points that would be better some where else. IE Crimson Scourge
Crimson Scourge, why not take it? Granted were not using plague strike on a rotation basis but being that blood boil is one of are major AOE skills the damage increase is to not be looked down upon. Would of been much wiser to put the 2 points from Aboms might to this.
Pretty much wipe all your talents from frost and max out epidemic, virulence, and 2 in Morbidity.
Why?
Epidemic will add more time to your diseases of course, just read the description, this even affects outbreak diseases as well.
Virulence, 8+9=17, with this are spells will never miss either, DND wont miss (yes it misses) blood boil wont miss, and if im correct outbreak is considered a spell and wont miss.
Morbidity, just taken for the increase to DND damage, it'll increase your threat quite significantly and well worth the 2 points.
GLYPHS:
Generally your correct on your glyphs, just change out death coil glyph for death strike glyph and you'll be fine. Don't ever use DC as your runic dump, that is rune strikes job and rune strike does a far better job generating threat.
NOTE: It is iffy about the death strike one, as we won't be stacking up RP as we use to it may be wise to just get the DND glyph for the longer DND duration. I'll have to test that out my self.
I'd post my talent build link, but i don't got the post count sadly.
