His magic shield and his passive make him better against magical damage than a "normal" mr growth would. His passive reduces 15% of all incoming magical damage, which is pretty huge. And it can not be penetrated like mr can. So even if you, theoretically, stack full magic pen against him, he will always negate a pretty good portion of the incoming magical damage.

Giving him a good mr growth on top of that would be doubleing down and not only make him counter mages, he would make him completely useless. Counterplay in this game is allways something you can play around, Kassadin is not an exception.

That's also where the armor nerfs came in. They give mages better chances to still do something against him in the early stages of the game via their auto attacks.
