Not sure what Nillo's wanting really. The guide would appear to be aimed at those that have tanked a dk whilst tank was blood spec, but are looking for a view on current modus operandii. Which IMO it has achieved.
Nillo, you know that out of all tank specs blood is the least hand-holdable, and that tanking more than any role is subject to variables.
I personally prefer an approach that provides a framework for experience to teach you how it is for yo. Rather than a prio list with all the conditions in there actually are and hammering that list with "ifs".
As for talents, lichborne is a personal thing imo, I don't generally spec it because I don't use, perhaps I'm simply not good enough, but I could never get away with pooling enough rp for the
talent to be worthwhile, outside of assisting with very specific spike damage.
