I'm pretty sure I've done higher on Spheroids than would be possible if they weren't weak to piercing, but okay.

I don't know what my DE numbers are on normal monsters, because I've only been killing goofy stuff like Jailer of Temperance, Ix'Mnk, etc. or doing STP Fusetto +2 trials (I spammed wasp sting) outside Abyssea since I got Twashtar. On the monsters that I do fight, Dancing Edge regularly does better than unstacked Rudra's Storm. There are still times when I prefer Rudra's though, of course.

My favorite thing to do with Rudra's is mini-zerg. I build up 300TP and 5 FM between fights and then pop. I generally put up Haste Samba and Saber Dance and get 300TP back for SF -> NFR -> Rudra's -> RF -> Evisceration. If I'm /SAM, I can go Sekka -> Evisc -> RF -> NFR -> SF -> Rudra's to close with Rudra's. If I get lucky, it can do over 12000 damage. After that, I just ride Haste Samba/Saber Dance/AM3 until the monster dies, then farm another pop and build TP. I hadn't thought about doing it before, but I could throw Building Flourish in there before the first WS for a little more damage even.

I think my priority when servers come back up will be to test Striking Flourish crit rate with AF3+2 body.
