There is a HUGE DIFFERENCE between how you, as a DM, should react to a player who intentionally takes poorly chosen spells knowing full well that his decisions could screw him over, and how WOTC, as game designers, should react to people's desires to take suites of spells which, in the present system, could screw them over.Neat or not, I'm not going to have sympathy for the player if he finds that all of his spells aren't of much help against a red dragon, salamander noble, or barbed devil. And if the monster is appropriately placed, I'm not going to change the monster just so he can feel useful. He's going to have to creatively dig his way out of the hole he dug for himself.
