I agree, ideally it would be handled the way you are doing it. If it doesn't work though I hope a pet would be on the table. It doesn't have to be for everyone, only casters of course. As for them being OP, have you seen the ultimate weapon on a warrior? It is crazy dps. I would even venture to see about having multiple weapon types on the pet as the UW increases. Hail the pet for a selection of a couple different weapons that he could have. One being aoe damage proc, another being an aoe root and another being some sort of group heal. The idea of the rune is to keep the pet alive. The scaling of damage and adding of different weapon choices is where you could add power as it scales up.
I like this a lot. Making note for future reference >_>
It might not be a bad idea to make it a shield (no back slot) for casters. That way they don't give up an epic click which other classes don't have to do with the 1h UWs. No melee class would give up a secondary slot for a shield instead of a weapon so that wouldnt be an issue and you could make the click effects whatever you want.
Hmm noted. Maybe not so much a shield as everything has shields. Possibly some badass looking offhand? (any ideas?)

EDIT: Why not just leave a staff graphic actually? Gogo dual wielding like ye ole' Gandalf?
