Cloud of Daggers also deals damage on a miss, like Reaping Strike. This really adds up over a long solo fight, for instance.
On a non-human I -might- agree, but as a human this will always be one of my 3 at-wills. Fighters aren't there to damage, they're there to be sticky. With heavy blade opportunity, you get +2 (sure strike) + wis + probably a +2 from combat reflexes (or whatever that feat was called) to attack on OA's. These OA's aren't there to damage but to make sure that ugly brute stops moving past you to hit the squishies you're protecting....Sure Strike (Fighter) should be graded -1: never take under any circumstance. These feats are usually outperformed by a basic attack (dependent on your ability score mod and other damage bonuses your attack might have). See this thread for the numbers: Analysis
