So something interesting I have stumbled on with AoE tonight while spamming dungeons.

I started opening AoEing with Gekko>Kasha>Kaiten+Tenka and then swaping to Gekko>Yukikaze>Kaiten+Tenka and then switching to Kasha>Yukikaze>Kaiten+Tenka and repeating this rotation of changing between Gekko and Kasha, keeping both buffs rolling with out any problems, spending extra Kenki on Kyuten and this rotation is actually providing a massive DPS increase over the standard rotation and I can't really put a finger on why that is.

About the only thing I can think of is i'm getting a much larger potency with Gekko and Kasha combos on single target and still getting Tenka+Kyuten AoE potency and combined is giving a bigger DPS gain then a strictly AoE rotation.

I've tested this with about 4 more dungeons tonight and i'm consistently out DPSing the strictly AoE rotation by a good 400-500 DPS.
