^ I like the spell tricks, etc. It's the sort of thing I've been advocating. And, it's what PF has tried to do, I think, with their Bloodlines. The problem is, most of their bloodlines suck. I'd also like more class abilities for Wizards, but it's sort of a non-issue as they have a panoply of great prestige classes. One easy fix is to give some of the less-used ones full casting and use that to paper over the Wizard's lack of class abilities.
The thing is, there is a huge gulf of difference between being able to cast an occasional spell when it's handy -- especially a great spell that lasts 24 hours or that you're going to persist or whatever -- and having to add it onto your spell list. Anticipate Teleport is a great one for a Wizard to have access to. No Sorcerer ever expends his spells known on it. There are a fair number of these in D&D, at least, such as the Heart of X spells that last for hours on end. That kind of cherry-picking is extremely powerful as there are a fair number of potent (arguably "broken") spells out there. There's just a lot of spells in the game.
And, as we've noted in this thread, the one selling point the Sorc has -- lots of spells per day -- is meaningless after about 9th level. And, there are whole classes of magic items that are iconic to D&D (wands, staves, etc.) that obviate it.
