Synergises with Ryze, Manamune and Archangel's. And, the mana is often necessary just to make the champion work. Eg. AD off-tank Nidalee can make very good use of the extra mana, while loving the CDR that Randuin's just doesn't provide. This isn't to say that most champions can't just buy both (yes, the passives stack; stop asking).
