Why TBN is a powerful but poorly designed ability.

[SyzzleSpark]

Isn't Exdeath's buster Magic based?

...Doesn't that basically mean DA-DM's not obsolete by virtue of a raid tier having magic busters?

Unless the tank buster hits multiple times in a row, TBN+DM is better bang for your MP.

Any single-hit magical tank buster will be almost as if not better mitigated by TBN+DM, and TBN will refund its own cost whereas DA+DM will not.

Lets say you have a TB that does 54000 damage in one hit. Lets say you have 45K HP. Mix of fending and slaying, some HQ food, whatever.
DADM = 37800
TBNDM = 36900, plus blood gauge.

If it does 54000 spread out over 6 hits of 9K...
DADM = 37800
TBNDM = 38250, plus blood gauge.

Its hard to argue for DADM really.

I agree, though you could have made these excellent points with 1/4 of the text.

Very true, its a problem. However posting on these forums for a while has shown me that people will misinterpret your words if you don't say the same thing in at least 2 different ways.
