Funny thing about that... you don't need a ton of stuff to optimized ToB, Cleric, Wizard, Druid, Sorcerer, etc etc etc... Actually you don't usually even need to ask the DM for the most broken stuff in the game (core wizard, cleric, druid) since you know it is core and for some reason people think it is the most balanced stuff.
You don't need a ton of stuff to optimize these classes. And the PrC's usually don't help optimize them ... Really going straight Druid/Cleric/Wizard is pretty dang optimized.
Heck even the Charger builds you need very little to optimize.
However the Monk needs soooo much more just to get to a piece of the pie.
