No reason to make it personal; I don't even have an Ifrit's Bow or Mogbow.

But if you have more than two archers, you are going to slip on the Bloodletter cooldown (80s, staggered by 30s = fine for two archers, not fine for three archers). And if all three archers are slipping on a cooldown by 10s, I don't see how the gain from Bloodletter procs makes up for the loss in personal DPS. As far as I can tell, Bloodletter does zero damage during the debuff and still just procs the ending damage.

I acknowledged the power of BRs once you proved it. I have no issues admitting when I'm wrong. But we're all trying to maximize overall damage output.
