I don't get when or how to use this Technique from Path of Waves.
The attack roll is against Vigilance, and you get the disoriented condition. And it makes Fatigue damage+1 for each extra two successes, with the possibly of spending opportunities for doing a crit if you incapacitate the opponent.
But we already had the Crossing blade, that was against TN2 (usually lower than Vigilance) and did damage equal to deadliness + 1 for each extra success (it doesn't crit if incapacites, but takes the opponent out of combat anyway and you can kill him easily next round if you want to). Or the Rising blade, that crits automatically if the opponent is incapacited. All of this at rank 2 instead of 4,and with no need to become disoriented after the attack.
What am I missing with Reverse draw?
