Manamune is for AD champions who OOM is a way of life, like Yorick/Urgot/etc. Or for Blitzcrank who likes a huge mana pool because of his shield and doesn't mind falling behind in AD because he's mostly about the CC.

Manamune is for the mana/mana regen it gives, if you want AD then there are other items which give more use.

Also Jayce's W restores mana every autoattack in hammer form.
