True, but that's one of the reasons why magic beats the everliving hell out of melee. They can do effects that are auto-win and melee sits there with a stupid look on their face. Magic beats Melee and most Magic requires Magic to break it. I believe it has been said before and might very well be said after this; "Melee should have nice things too."
Which is a good reason to throw off anything a 5th level wizard can inflict. Where it gets sketchy is where 15 levels of increased wizard power still mean nothing against that same warblade.
If you don't like wizards, how about gods? If a deity curses you, you probably shouldn't be able to shrug it off next round.
