With this spec (or something similar), you are trading a few abilities in fury that are good but not incredible (enrage nerf, deathwish nerf). You would be gaining Incite (+15% crit to hs/cleave/tc), last stand, AND best of all Toughness (which increases armor from items by 10% AND reduces slowing effects duration by 50%!!!).
Potential? I think so.
You can do something similar with fury also. Try it out.
Thoughts?
