it's a lot of mana and some ap for a support, however useful that is to you.

Personally, I'd go with finishing actual support items like shureliya's, mikhails, aegis, zekes, or Shard of True Ice. Raw AP doesn't help many supports as much as it does ap carries, instead support items allow you to stack what are essentially bonus abilities and extra stats for your team.
