I think Ill just agree to disagree. LOL!!!
As for sorcerers, their mechanics do suck. They rely on the trappings of traditional wizards to cast spells, I see intuitive magic as being unique to the individual, with no trappings of any sort. I would never have a sorcerer use components. It's just isn't very logical. The spell systems, while only moderately broken, does present a few problems when it comes right down to logistics.
I have always believed that when a person learns a skill or a trick of some sort, they are not going to forget it, short of amnesia or brain damage. I myself study martial arts and I still remember all those seemingly useless moves that aren't as nice as the more complex moves. Sure those tactics might seem useless, but I doubt someone is going to forget them. that would like forgetting how to ride a tricycle just because you now ride a harley.
It's a load of B.S., and for me, it isnt about making things more POWERFUL...I too dont like the excessive hit dice, though I do like the flexibility of a plethora of maneuvers that just don't seem to exist for most combat oriented characters. They need more monk oriented classes that allow for energy effects (even if they only do +1d6 or something) and they need more classes that bypass alignment constraints that are similar to the monk class (not everyone likes being lawful just to get martial arts skills).
Perhaps they even need a class that is a blend of fighter, monk, and warlock, without the alignment constraints.
And then there are all those class with limited spell progression, they'd be better off just erasing the spell progression and making classes like bard a prestige class, which is kinda what it used to be in OLD d&d.
Dont get me wrong, I love the system, but I would be lying if I said it wasnt flawed.
As for Vancian casters, I have no idea what those are.
