Do you think the devs intended multi-flare blm?

If your BLM is AOEing spam flash until you're OOM or comfortable on threat, then build mana back with riot blade.

Agreed, I do this when farming Brayflox HM and very rarely lose hate, even in parties with two BLMs. The only times that I do I'm thinking it's more of the enemy not being close enough for flash, as opposed to Flare generating more hate than flash.
