Well yeah -- clearly they wanted to show that his Spriggan magic wasn't as useless as Leafa thought it was (thanks to his already-established cheater stats), but even I thought it was a bit silly that they foreshadowed it so completely obviously in the pre-OP segment. "There may come a day when your Spriggan magic saves us all! Hahaha..." Ten minutes later...
In the end, since Kirito has to reach his goal by week's end, he basically gets thrust right to the forefront of everything right away, so he is incredibly overpowered in this arc. All in all, though, it doesn't really serve that much of a purpose other than getting him from Point A to B, because all his "power" doesn't really solve the fundamental problem of what he and Asuna are going to do once they meet up. So I guess I sort of take the "overpowered" thing as a necessary plot device in this arc. At least they established it from the get-go.
(Edit: And that aside, I often play healers in MMORPGs, so I don't think there's anything lowly about being a supporting class. So I didn't take it as a put-down. She obviously had the superior magical skills anyway; he just had the one Spriggan-exclusive spell they needed to play the frontline role. Even if he got to "look cool", he couldn't have done anything without her there.)
