What? He's one of the best lategame aoe'ers in the game, ratio-wise. AP Ez is weak early, and strong late, as he requires lichbane to be really effective and scales very well for having 2 aoe's.
It's AD that tapers, off, as one is required to rely more and more on autoattacks rather than mystic shot lategame (it just doesnt apply enough multipliers) while his base magic damage from the other three abilities becomes less and less useful and he's forced to use them for utility and sniping.
AP ezreal is more of a waiting game with a really weak early game (until lichbane) and then becoming a mage-carry late with high-scaling, low-cooldown aoes and great poking, while AD is more of a "dominate from level one and win before anyone catches up" build (or at least last time i played him that way it was).
