This may seem super trivial, but on my mage I rarely get to use wand transmogs because staffs are almost always superior (dps-wise). I think it’d be great if we could have the ability to transmog any weapon-type our class can use regardless of what is equipped. The technology exists (you can do it for legion artifacts!); so, please, let my poor mage actually use a wand!
Thanks! 
100% agreed. Played mage in BfA and loved whenever I got to use a wand because I’d always mog it to a sword and I love the idea of a caster using their focus in their off-hand to cast and their main-hand being a sword at the ready. Sucks having to use staves.
Even as a fury warrior now, I’d like to swap out my two-handers for one-handers mogwise as I feel like the two-handers look kinda silly.
