The game is fun, like a lifetime of fun, and totally customizable if you don't like parts of it, and I have players who don't abuse any of this min-max stuff. I just feel offended -- kind of like you feel when, politically, someone does something totally alien to you, like voting to give [Group X] even more power or having a first-grader arrested for carrying nailclippers. It means everything about their worldview must be totally opposite from yours.
I dunno, can you get specific? Cuz then you can maybe get some specific advice. Generally railing against a mentality isn't going to get at your problems and help repair them. Narrow the focus. Look at specific problems.
I guess if you aren't looking to fix the problem, and just want to commiserate about some of 3e's insanities, I can't object.

The fixes for Shapechange and the word about Shield of Law are solid advice. I know late 3.5e books introduced "change into this specific creature" type spells, which seemed to me to be a good idea, too. But if the players aren't abusing it, there's probably not a huge problem, right?
I mean, at the table, when you play the game, this isn't ruining your fun, is it?
