You need a 2 button stick. Slash can be beaten without grabbing him, and doesn't block all your attacks. Using one button however is a severe handicap! On the whole, most arcade players will be doing a fair amount of grabs as they take off a lot of energy, score you a lot of points and can round off a combo. There are also several frames of invulnerability to some of the attacks.
You're right though, we've got to look at the AI on the whole and get it up to scratch.
