I don't know, I'm still thinking it's just not that great. Sure, it's nice, but put it into an actual usage perspective. It would only affect the initial attack, so no maximum ongoing damage like with Flaming Sphere, just the first attack, wouldn't affect zone damage (except for the first attacks) and you'd have to decide to use it before casting the spell. Imagine if you cast it and only hit one person in a zone of ten (I've seen this happen, and more often than not, wizards tend to only hit about half the targets)?
