Like I said, the MP cost is what allows it to be on a shorter CD and give you more uptime on it which is not something to sneeze at, so there's definitely a good reason to make TBN cost 3000 MP. Anytime Square ties utility to some kind of resource, they always give it a shorter CD like SAM's Gyoten, PLD's Shelltron, formerly WAR's Onslaught. Hence why I would be opposed to removing the MP cost entirely so as not to lose that aspect. Now could they just have TBN automatically grant a DA proc as soon as you use it or when the shield expires to make it fully damage neutral? Sure I guess, I personally would say it's really not that big a deal and to time TBN better, but that option is there.
