I never said Gragas IS AP on hit, I said that I like to buy AP on-hit on him. That's because he already has a good melee damage, benefits from cdr and AP and one of his damage sources brings him to melee range. After some other ap AP (armguard, RoA or Rilay), nashor is a strong addition to him.

What I meant with most mages could use Nashor is that if you build AP for some other reason and you have time or other reasons to autoattack, nashor could add a good dela of damage to your combo, either if you already have on-hit damage (lux, ori, ziggs, kennen) or long cooldowns (Morg...).
