TBN vs DA (analysis and discussion)

[Shinkyo]

Doesn't that only matter if you hit an invulnerability phase before a Soul Eater combo line finishes? I mean what level of GCD count are you doing ahead of time to think "If I bloodspiller now, 9 minutes down the line I lose out on Souleater"
>_>

It also depend when you use/get that Bloodspiller. If it’s during a rDPS buff (e.g. Trick attack), you’re more likely to make TBN a small DPS gain.
But overall, TBN is neutral. It’s sometimes a gain, sometimes a loss and you have little control over the certainty of that outcome.
However, TBN always carries the risk of mistiming it (less likely in 4.2) or capping blood, whereas DA is always consistent.
