No one will change anyone's mind in this thread about the merits, or lack thereof, of Vancian magic.
I like the Vancian magic system - but I think there are ways it could be made more flexible.
- Why not have some spells in the Vancian lists that can be cast 'at will' when learned?
- This could be paid for in 'perma-slots' - that is you sacrifice, permanently, say 3 dots at the spells level from your available slots (and maybe a Feat too).
- Naturally, this reduces the flexibility and quantity of a simple fire-and-forget spell list, but it gives the option of basically making the magic more spontaneous (like a Sorcerer).
Only some spells can be perma-learned in this way (mainly things like magic missiles, some boost spells, definitely all the cantrips), whereas others always require preparation (rituals) as they are too complex and/or powerful (no permalearned Wish spells!).
For example, if a 1st Level Wizard has spell slots for 4 Cantrips (level 0) and 2 Level 1 spells, he could permanently sacrifice 3 of his Cantrip Slots (and a beginng Feat called "Spontanious casting", say?) for one permanent Cantrip that he can always cast at will. He would only have one more slot available however to choose other spells, and would never be able to change his permalearned spell or trade in the old one (unless maybe, you had another Feat called 'Deconstruct Magic' which allows you to release them back to other slots?). If a character could add more spell slots to his other levels (from Int boosts or just natural progression), he could carry out the same thing at all levels.
Of course, this may make the Sorcerer as is, a redundant class. If Wizards can have the option of gradually, or partially, turning their character into a spontaneous magic user, then what would the point of playing a Sorcerer be? However, I feel that the Sorcerer could be reinvented as only being able to choose 'At Will' Spells, whilst also being boosted by having better weapons, armour and combat stats - Like Elric.
