Well yeah, since I've cast it under CBM, I've seen it cast under CBM. I don't see what that has to do with anything anyway, since like I said I don't have the MP experience to comment on how widely used it is. I have used the spell and know how powerful it is. I'd say massing archers with fire arrows is a much better idea than forming up evocation barrage squads, under the vanilla fire arrows values. It takes only a few mages to provide a lot of extra firepower and they can continue to cast spells after the flaming arrows. To match that kind of firepower you'd be talking a lot more mages casting evocations.

I think you overestimate the amount of fire protection your enemy is going to field. Regular armies are still around and without total fire immunity until the lategame sees them entirely replaced with items and summons.
