DRK - Excessive Dark Arts

[MoarLegion]

Only it doesn't, since outside of using it for defense or using it to get an easy 50 blood for Delirium, TBN is a damage loss.

People keep saying this but I fail to understand how. You're taking 140 potency of MP and turning it into 380 potency, the MP cost of which is paid for by the time you can even use TBN again. You're only delaying 1 SS/SE combo per minute, or half a dark arts and 10 blood, so you're not delaying your mp regen by any significant amount.

Provided you always have CnS paid for, I cannot understand how turning 140 potency into 380 as often as possible is a DPS loss.
