Fair enough on comparing things one on one, but my point still stands. TBN on its own is powerful, but like you've said before, its how the whole kit comes together. Equilibrium is up about as often as a dark knight would optimally want to use TBN, but it is 10k weaker. Whether you delete the damage or just heal the damage makes no real practical difference.
Does TBN outshine equilibrium on its own?
Yes.
Does TBN outshine Nascent Flash on its own?
Yes.
Does TBN outshine ToB on its own?
Yes.
Does TBN outshine all of these taken together? My answer here would be no. In fact I think the weaker statement: "Does TBN outshine Nascent Flash and Equilibrium together" is also a no. Of course we could put TBN up every 15 seconds like clock work, but I don't honestly think you can pop it that often through autos alone, I usually can only pop it for a raidwide + 2 autos, which means that we could block more damage but at a major dps loss.
The relevance is that we previously disagreed that Living Dead could or could not use some light adjustments on healing requirements based on the power of the defensive kit. But I don't honestly feel that the defensive kit is actually strong enough to support that statement. Even if you look at the "least defensive" tank, GNB, its kit is fairly close in damage deletion power.
