I like athletics for mages. only because you probably want a bit more than 2 in stealth and disquise and palming aren't really needed. but 2 points in gymnastics, running and swimming is just about perfect for a "pure" mage.
chaos world is an excellent debuff, another great one is net bind, because you reckless case it with your aoe spell to prevent the enemy from taking an interrupt action and running out of the target area.
mind probe is probably more useful than analyze truth.
every mage should have increase reflexes, no way around it
combat sense is also excellent
you don't need both ball lighting and fireball at the beginning, if you want two aoe, go with blast
I always recommend trid phantasm, because not ever problem can be solved with damage, and it's such a flexible spell
other excellent can't be replicated by other means type spells

sound barrier
