'Fear Me!' is only useful if you build around it. That means a higher Tactics attr., FGJ!, Locust's Fury, Flurry ----> auto-attacking. Lacks greatly in the damage department though.
As an avid A/W, I've found [skill]Distracting Blow[/skill] to combine with a Moebius Blossom spam build very well, though it requires excellent timing.
The main thing to keep in mind here is that any Moebius Blossom spam build excels in pressure damage rather than on quick kills. This means you're going to be at a target longer than yer average SP Sin, and hence will draw more attention to yourself. You need some guaranteed monking back-up or *gulp* bring a self-heal. As an A/W, Restful Breeze is a no-no... damn shame. Here's what I ended up with for AB and RA... (EDIT: in RA, Shadow Walk = Rez sig)
CS 12+1
DM 11+1+1
SA 6

I like Dash but I guess you could put in Dark Escape. SW-Dash has been so good to me I wanted to hang on to it, though SW and Shadow Refuge definitely lack synergy. Then again, I often find myself just going Dash-LMS... while Refuge is kinda bad it's the best thing available for an aggressive A/W.
Really this build is just a variant of the Moebius Breeze sin. How Horns of the Ox compares to Distracting Blow is debatable after HotO's huge nerf. However there's no doubt Restful Breeze is a lot better than Shadow Refuge...
You wouldn't believe the **** I can pull off with Siphon Speed-Breeze

That's DEFINITELY a route to consider!
