It's a lot of work to implement solid combat stealth. I've played Baldur's Gate a lot, and have messed with the codes too, so I have an idea what it's like if you want AI to use and counter stealth in a reasonably smart manner.
So I suppose we could just start with the popular "2 AP sneak". By default, you need Sneaking rank 5 to completely negate movement speed penalty, and I think that's alright. Then Guerilla deals 250% damage? These could certainly be starting changes - not too radical, and sounds reasonable to me.
