This conversation has been discussed and conquered in a few previous Fury Warrior threads. I'll post again here for more clarification.
Weapon x - y damage & speed no longer factor into any of our special abilities, except for the DoT from
Rend & white dmg - to a small extent.
The other 5 damage abilities that we have are now entirely based off AP. I know its hard to wrap your head around, myself included, but Its true and here is proof.
Bloodthirst : AP x 62 / 100
Heroic Strike : 8 + $AP x 75 / 100
Victory Rush : AP x 56 / 100
Execute : 10 + AP x 0.437 x 100 / 100
| $AP x 0.874 x 100 / 100 - 1
Thunder Clap : AP!
Taking this new information into consideration, this theory is correct. Even a lvl 1 dagger with +1 strength will out perform SF when applied to our special abilities. I have done the necessary testing to confirm this, and it is confirmed. (don't use daggers fyi - rage gen is bleh at best, its just a no no)
There are a lot of choices for 1h swords with strength. What you have to ask yourself is, what works for you? Some have extra strength, while some have hit rating, etc. But to narrow it down, here is a list of viable options - all surpassing SF.
Butcher's Slicer
Legionnaire's Sword (or alliance equivalent)
Razor's Edge
Baron's Scepter
Gutterblade (no longer available)
As for enchants Crusader x2 or Crusader / +15 strength, as many have mentioned above. Hope this helps, cheers!
