Hmm. I see benefits in most of the other changes they've made, and none are as huge as stripping out one of the base attributes.
Wizard schools weren't a focus until 2nd, multiclassing as it is now is essentially made for 3e (and doesn't work well), and the flavor stuff changes with campaign settings anyway.
