I said some posts back that I am ok with adding a mechanical line like 'Range: 150 ft, Radius: 20 ft, Effect: 8d6 fire, Save: Dex, halves' and removing that from the description, so it is not redundant. I am not ok with that being the entirety of the description, the flavor text should remain.
"A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of flame. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one.
The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried."
is more flavorful to me, 4e seems to go for the bare minimum possible
