If you cast fireball, you can deal up to 10d6 damage, which means up to 60. Cut that in half for everything that makes the reflex save (likely) and remember to account for spell resistance and all the creatures that have resistance to the element type.
If you spent that same turn casting haste, how much damage would you deal? You would have to add all the damage together for every extra attack from all your party members, animal companions, and summons over the course of the battle. Not to mention the increased AC and better positioning.
Same turn, one was spent way better.
If you really want to throw 1337 dps dice, other classes do it much better than Wizard. Look into Ranger, Sorcerer, Fighter, Barbarians, Monks. Fighting is all they're good for.
The problem with buffing spells, however, is that we only have two people who use regular attacks, and only one of them is actually designed for damage. Though you are swaying me back toward my bard/paladin, actually.
