Why not just call it it a rod because that's what it really is?
The reason for this was to standardize the difference between rods and wands. The only reason rods get no love is that people have this image of a wizard and his pointy stick stuck in our collective memory from Gandalf to Elminster and Harry Potter.
So now we're stuck with sucky wands and nobody really wants to be a wizard with a rod. I get it. However, I'm not willing to rewrite the rules just for the look of a wand.
Rename this class as Rod Adept and watch me beat the pants of the Wand Adept.
