We obviously won't get one until after the class reworks
Id love two new classes.
Monk and Dwemer engineer
Monk basically look at poe2 and steal everything from that class, especially the bell charm that you throw out , it enlarges and hit to make your damage AoE mechanic. Maybe class mechanic so that it doesn't use the weapon it has equipped but still can use weapon skills( yes even bow skills, it shoots chi)
Dwemer engineer will be the first non magic eso class, simply someone that's studied that technology and uses it to engage in combat scenarios. Kind of like Sotha Sil or Kragenac. Basically the clockwork apostles we fight in eso.
