The new motto is: "If anyone is using it, it must be too powerful." Thus it gets nerfed. I seriously question many of the spell changes that they enacted from 3.0 to 3.5. With saves for every spell, spell resistance, attacks of opportunity, counterspells, and numerous other things, there are so many ways to counter wizard's spells, why did we need to do these changes. The quest for "balance" is destroying the game. Maybe instead of nerfing the few spells that wizards always take in an attempt to "balance" things, maybe they should be raising some of the other less comonly used spells.
