Interesting that your aoe rotation utilizes Goring Blade Kakita (Nice to see you btw, we're in the same tank LS)

I like the rotation, but I personally use the old Flash -> Fast -> Flash -> Riot -> Repeat (peppering in sheltron) primarily out of habit (from not having a cap for the riot blade combo for so long) but also because I find I won't usually get a full duration bleed because things die quickly. Once you're down to 3 mobs do you still use this? I personally use an alternating Rage of Halone and play a little game where I try to keep all three mobs debuffed while putting up at least 1 pacification or stun per Halone combo.
