Astral Admin - Mwahahaha!
I don't really worry - typically the wizards have all kinds of spells (one players' PCs are regularly chastised by his compatriots for 'never having any useful spells').
FWIW my first magic user in 3.0e was a sorcerer, and I was determined to avoid all the classic 'must have' spells - so planning their spell list I eliminated mage armour, shield, magic missile, invisibility, fly, haste etc - and had a ball with the character! Regrettably the spell and metamagic changes in 3.5e knackered her spell list and I had to make several changes to fit into the 3.5e world...
