WoTC just seem to be trying to make the system as bullet-proof as they can, how successful remains to be seen. The only problem most people have is that they are over-doing some things that 'can' be abused by the lowest common denominator of gamers.
For a lot of us, we see the loophole, area of abuse and we dont use it out of respect for not giving a GM greif/hogging the spotlight over players.
As a result not much is going to change for some of us and we'll probably keep what we like out of 3E and 3.5E if we dont think its going to throw the game out of whack too much.
For other people who enjoy tearing a rules system to pieces to make a whore of themselves with the rules then theyre going to find that area a bit harder to molest because 'its not in the book' anymore. As a result the game just got a lot more bearable for some GM's that have people that cause those problems.
Like most things in life, you take what you like and keep it, discard what you think will be annoying and keep on rolling.
To be honest, a lot of this can be solved by a GM just saying "Not in my game" and a player(s) not wanting to cause anyone too much hassle.
Failing that, a good punch in the face can work wonders on some people...
