Resiliance already covered most of it, though there are a couple things I should note:

- Sasuke's barrier is his Mystery, meaning he can cancel out other people's barriers. This is an advantage in its own.

- In addition, when upgraded with skillbooks Sasuke's mystery can dish out quite a lot of paralysis. (up to 12 affected characters if I remember correctly?) The only problem is that this takes a while to execute due to the nature of his Mystery.

Overall, I'd still rec Darui, though Sasuke still has his uses.
