Brayflox HM - All sorts of Chaos

[Lemuria]

While I believe you that most don't pull to the top, the reason many do (myself included), is that you don't have to deal with the bomb aoe's if you pull up to near the stream.

I'm not entirely sure that's accurate. Several groups who pulled up the ramp with me as healer found themselves dodging the AoE from the cannon the whole time, right outside the boss room. I believe a key mob needs to be slain before the boss leaves you alone properly, otherwise you'll be dancing around them right up until the boss.
