It has cooldown reduction, which plays into Ezreal's skill set (Ezreal has always been an idiosyncratic carry partial to different stats).
Anyway, having this item when your opponent has a BF sword/Longsword is an advantage, to be sure. But it can't go toe-to-toe with Bloodthirster, Infinity Edge or BotRK in terms of raw power.
