More than likely yes, maybe the AOE spell would have to have it’s mana generarion cut by half as well; to balance out Scatter / Scatter.

Also if it did have that AOE buff to its next spell, it would open up more variety in spells, rather than introducing a new AOE cast spell, like Verwater or Verblizzard (which I’m not against of course)

As far as an ancient spell being AOE, perhaps a new ancient finisher in the coming expansion could give us one, I’m down for a Quake / Flood / is Freeze AOE. But not all.
