Oh. My Talos.
I don't know if it is something to do with the swords, but whenever I use the Elemental Fury shout in combination with two scimitars, the world bends their knee to me.
I'm currently playing a Redguard assassin/thief with dual daggers and dual scimitars as backup, and whenever I have to utilize those lovely curved swords, everything around me suddenly is victim to the hurricane.
I've tested this many times and while daggers are supposed to be the fastest-swinging weapon, the Scimitar swings twice-as-fast when using only the first word of Elemental Fury. In combination with the Redguard's stamina regeneration racial bonus, I can spam power-attacks and become a literal tornado of death.
My character is level 28-30 and with an unsmithed and somewhat perked Scimitar can almost insta-kill a Draugr deathlord. About 2-3 power-attacks, he is down.
When going into 3rd person in attempt to view the power-attack animation, I had trouble because it was over so quickly. He starts to swing, then blurs into a spin and it's over, no more than a second in total.
I don't know if others know about this and/or utilize this, but it is truly awesome!
