Well we agree with that; it's just that I think it'd be brainless to specialize...Liquidsabre said:Being a specialist is practically a no brainer.

Honestly; your argument is only flawed in that the wizard's normally limited selection almost never leaves spells out from other schools. Almost every wizard would need access to spells from each school. To make my point...
Identify (Divination)
Dispel Magic (Abjuration)
Teleport (Conjuration)
Fireball/Lightning Bolt (Evocation)
Invisibility/Blur (Illusion)
Polymorph (Transmutation)
Hold Person/Monster (Enchantment)
Ray of Enfeeblement (Necromancy)
What it boils down to for me is Wizard = Flexibility, Sorcerer = Quantity over Quality. I don't see an option where a specialist wizard is really a better choice than simply playing a sorcerer--unless, of course, you're using the Unearthed Arcana variants; and even then it's still a tough choice.
I can't think of a school that I don't plan on at least dipping into. That'd be denying an awful lot.Liquidsabre said:...so you might as well specialize and pick the schools wth spells you don't plan on dipping into anyhow.
