Drk: worst designed class

[Reynhart]

You'll almost certainly end up wasting blood by going over 100, or wasting MP as some shields don't pop.

"Wasting blood" is not really a problem. TBN breaking is DPS neutral because it costs the same as DA, so as soon as DA-TBN gives you two BloodSpillers, it would make up for its cost. With 15 Blood per shield, it would allow you to break even if 7 shield breaks, and, since out of Blood Weapon, you only gain 10 Blood per combo, 6 shields + 1 combo would reach 100 Blood. If all 8 shield breaks, you're even, and you've mitigated every damage you can, so the wasted Blood is not that big of a deal.
