4.05 - Tank DPS comparison

[Reynhart]

The argument is not about using Bloodspiller. Bloodspiller is a potency increase over our average GCD combo. What the math is proving is that it's a DPS loss to spend 2400MP to get an extra Bloodspiller(via TBN) versus using that MP on Dark Arts.

Then your whole explanation with the "opportunity cost on blood gauge" is off-topic since using or not using Dark Arts changes nothing on what Blood you naturally gain.
What you should compare is two GCD chains where you spend your MP differently. And since Bloodspiller is now stronger on its own than DA-SS, I doubt it's still a DPS loss.

I've added the math to my previous comment. Needless to say, I didn't just pull this out of thin air. The more educated people are about the reality of the situation, the quicker we can be on the same page about what needs to be buffed, and why.
