"Swain, for example, doesn't need quite as much mana regen"

Swain needs to rush RoA, he's easily one of the most mana intensive ap mid laners since his ulti does so much for him. Did you lane CC? Better toggle ulti. Do you need to prevent your lane from being shoved? Better toggle ulti. Do you need to trade? Better toggle utli. Do you need to leech some life? Better toggle utli.
