I think the issue lies here:

I don't think this is true at all. The 11th through 20th levels of wizard or fighter are
vastly more important than the 1st through 10th of the other class. That's why a F10/W10 is completely outclassed by a F20 or W20. The real value in classes comes at the top levels -- to balance out giving up the top levels of a given class, you have to give
more than the bottom levels of another. The
reductio ad absurdum is a 20th level character with the first level of 20 base classes. I think everyone understands that he would bring almost nothing whatsoever to a 20th level party.
As others have pointed out, it's exactly like Mystic Theurge. Everyone looked at it and said, "Oh my God! This is amazing! This is like two classes in one!" And a few days later, after it was played and builds were analyzed, everyone realized that it didn't really play as good as it looked. Each character, no matter how many options he has, still has just three actions per round.
And has anyone actually played a straight Eldritch Knight? It's just not that great -- I can't imagine anyone's Eldritch Knight outshined other characters mechanically. A friend of mine played pretty well built one in a game with a full wizard and a full fighter, and he constantly felt like he was 85% of the fighter and 85% of the wizard. And, as I suggest above, that's
not equal to 170% of a single-classed character.
The role of the Eldritch Knight is problematic, too. If you're emphasizing your wizard side (either through blasting or crowd control), then you're "wasting" all that BAB you have. And if you're going in and fighting, you're either spending a lot of time buffing during combat or "wasting" your spellcasting.
It's a flavor choice -- a neat way to make a useful character that has a different style from straight wizard or straight fighter. Perhaps its design doesn't conform to aesthetic ideals of "balance" and "trade-offs", but in the actual game, it just doesn't blow away other characters.
