Wizards don't have to go out of their way to control the battle field. Blasts of all kinds flow naturally from the arcane.
Volleys (already the territory of rangers and rogues)
Stares (for the record I do think those are nice)
Dust/Sand (meh)
melee bursts (fighter and ranger territory)
Caltrops
but that's about it. How do you fill a power list with just those abilities?
How do even make any of those epic?
Wizards flow into the controller role so well large categories of iconic spells had to be omitted from their power list and then added in as dragon articles
