Ok so I've been going through a Lot of fflogs and DRK pov Clear videos lately and one thing I realised is that many people that definitely arent Bad at playing the Job Seem to be using TBN as a damage boost, using it as much as possible, sometimes even Standing in aoe on purpose.

But I always thought TBN is a small dps loss. Now Im not one of those clever people that do Pages of calculations to find Out what the perfect Rotation is but my thought process was basically this (assuming a GCD is Just 2.5s for simplicity):

If I do a souleater Combo and DA once I have (150 + 250 + 440) / 7.5 = 112 potency per second

If I spend my 2400 MP on TBN however I have (150 + 250 + 300 + 400) / 10 = 110 potency per second

Therefore TBN is a small dps loss right?
Please correct me if Im wrong as I Said im Not a pro Player lol
