^ usually I don't need blue til I hit 6, and you can't always depend on your jungler (especially one that's blue-dependent). Also, the mana regen is nice (if you're having E active early you're doing it wrong) and there are some cases where levelling up wall won't do jack shit for you (eg LeBlanc).
