Sona is based on stances, the combination of them, and is a charcter that does not interact well with any itemset, the idea was mainly to interact efficiently with the set, which is pretty unusual in supports. And, just in case... nerfing her damage output so that building AP is not profitable, doesn't mean she will combo well with any itemset, it just prevents her from being OP.
