Scrolls are, in my opinion, what makes a pure melee character viable. There aren't a lot of situations where you have nothing relevant to do, but the simple nature of having just the Man-at-Arms skills and a melee attack means you'll lack relevance at some point. Scrolls fix this; I see them as the melee equivalent to special arrows.
The only thing that's a little awkward is that the damage and chance-to-status on the damaging scrolls is kind of weak. I see a Freezing Touch scroll as a nice pull; I don't feel nearly the same way about a Blitz Bolt scroll.
