Ok, first off you are required by law to use Extraordinary Spell Aim with it. If you do not, you might as well just award the party XP and loot for defeating the guy you intended to use it and move on.
Once you've done that, you can take advantage of the fact that Conjuration: Creation > AMF works both ways by shooting orbs while inside it. Or you can just make a gish. Which is what you're already halfway to doing anyways.
I think you miss the point of Extraordinary Spell Aim.
That feat makes and AMF "not effect" you, therefore you can cast ANY of your spells out of it, not just instantaneous conj.
You're right, every wizard/sorc should have it, but I thought this was already a given.
Also, not sure most people realize this, but the feat causes it to "not effect" you, it doesn't say anything about it not effecting anyone else, and by extension their spells. So if you have an ESAed AMF around yourself youre effectively immune to all spells, except those instantaneous ones; most of which can be taken care of with a ray deflection or friendly fire.
Or you could just pull the whole ghostform trick. Normally you would blink out, but since the AMF doesn't effect you it wont effect your ghostform. However, for purposes of interacting with other's spells and abilities you are effectively an incorporeal creature inside an AMF. Now you're virtually invulnerable to pretty much any form of attack...tack on a forceward, and a friendly fire and I think that basically covers everything except a non-magical seren quarterstaff or other wooden weapon. The only thing that can stop you is, of course, another AMF...and maybe an iron heart surge.
Creative uses of AMF are the only way to combat high level mages aware of tricks like this.
