Female wizard ought to be the Black Hole/Archon type mage as well. Khadgar can do Arcane mage, but Diablo Wizard should be the 'manipulate time and space' kind of mage imo.
Spectral Blades, Arcane Orb, Black Hole... ults could be Archon or Slow Time. Alternatively switch Black Hole and Slow Time for E/R.

There totally is. Teleporting, Explosive Blast mage is crazy and hilarious to watch.
