Not that you can guarantee them being used close to the usage of 'Blood Price', so it will likely be healed by other means.
I do feel this whole thing is more a way to keep your current rotation rather than being something to 'improve' DRK in some way. All that really has happened here is that you can use TBN, then use Blood Price to forgo any sort of skill expression in using TBN and trying to get it to break.
Which is why I highlighted the minimal gain from that last edge in a burst window. You will generate the same amount of MP in a fight regardless of what you do. You seem to have this fixation that you need that 5th edge in the burst window, likely so you feel better about performing it. However, altering and adjusting your rotation to fit the fight is another way to express that skill. Not using TBN allows extra MP to be utilised elsewhere for minimal loss, for example, having an extra edge or even flood to go after adds.
