Who is Rod of Ages good for?

I'm curious, who exactly does the item Rod of Ages benefit the most in a game like League of Legends? Is it more suited for a mage who specializes in sustained damage over time, or would it be more advantageous for a burst damage dealer? Additionally, does the item's passive ability to gradually increase ability power and health over time align better with certain playstyles or roles within the game? I'd appreciate any insights you may have on the matter.
