If it makes you feel any better, a lot of people playing in China say Susanoo Sasuke is useless too. ;P;P

Decent...
Well, try darui, light main, ay and chojuro. All will get boost from barrier.
Use light boost as main passive, that way he boosts himself, ay and darui.
Chojuro and darui strike 2 times (for darui it's valid only if he wins the barrier). Ay attacks four times.
You sould do pretty nice damage.
It will however be a bit hard to link them combo wise, it will depend on your summons. But still, this team will have loads of damage.

Another one could be darui, guy, ay light main. (Guy gives tai boost and leech).
Darui, mifune, light, ay would be the 3rd.

I will later on, when I get home ;)
