What's wrong with it, you ask? You might not know if you don't use headphones. When Elemental Fury is used with dual swords ( mine are ebony ) a wind effect is made to sound from your swords. This sound is buggy in such a way that the wind sound can persist, and persist some more. And it is loud enough to drive me mad with hate. So, don't use it, you say? Yes, it is so bad that I choose to stop using it. Worth it for the sanity.

My only problem with Elemental Fury is it doesn't work with enchanted weapons.

Though maybe that'd make the game super easy mode lol even if you don't use the crafting 'exploit' lol.

If you are on the PC, you can get a fix for this http://www.skyrimnexus.com/downloads/file.php?id=456. They have some other fixes you may want to have a look at also.
