While I really dont forsee SE doing anything to prevent the ability to speed run Brayflox in the future, as really, no one is actually circumventing game mechanics to get ahead (in reference to that, remember AK before the fix, things were simply ignored), now it's simply killing everything much faster.

However...this particular idea, I could see them frowning upon. Because essentially what you're doing is just putting things on the hate list to build up the LB, for the sole purpose of only building up the LB, not actually fighting the mobs at all. So you're gaining, without risking. That will likely get changed.

In related news. If you actually need the LB to finish the second boss in Brayflox, your DPS is terrible. The only times I've hit LB in Brayflox SRs, is from people dying, which boosts the guage. In a normal encounter though, as a caster the damage from LB is nice to kill the adds and take a chunk of hp off the boss, but hardly worth it. Single target DPS would benefit from it the most, but then, I don't take melee DPS with me on SRs anyways, so there's no point.

Anyways, yeah, that wont likely last much longer now.
