The Chronomancer reveal was very exciting. Though I don't play Necro, I could see how the Reaper would be cool to those who do. Dragon Hunter and now Tempest have left me shrugging my shoulders. I'm trying to figure out why.
I'm not a theorycrafter. My reaction is purely intuitive, not based on reading through new traits and skills and looking for synergies, so maybe I'm just missing what the DH and Temp bring to their professions.
