Sure, but you have to know how to optimize in order to reliably build sub-optimal PCs.
Otherwise you're apt to get the guy who decides, "Well, I don't want to make my wizard too powerful. So I'll avoid taking any damage-dealing spells, and just use stuff like slow and glitterdust." And then the wizard dominates all the encounters, because those spells are crazybroken in 3E.
I don't agree with this. Taking a few optimal choices accidentally doesn't create an optimal PC. Also, if someone doesn't know how to optimize and just takes stuff to fit his PC, he an easily build a sub-optimal PC.
