So making equal-level Fighters obsolete while casting like a mini-Sorcerer isn't enough?
They get pretty much all the standard buff/control spells, and many of the nice utility ones like Phantom Steed, Teleport, Plane Shift, etc. They're very well-suited for their routine (have Eidolon crack heads while you buff the whole party, then do a bit of utility outside combat, especially with the Skilled evolution).
What spells are you looking for?
