Do you think the devs intended multi-flare blm?

You should be using hq mega/hq x-pot of int with that instead of x ether for higher damage(multi target scenario at least).

Negative. I've tested that, the X Int will put maybe 2-300 extra damage per hit, a little more on a crit, but prevents me from pulling out that third flare because of the mp issue. A third flare on AF3 w/Raging is far better than the boost from the higher int.
