Hello,
first of all, I'd like to say that I know seriously nothing about balance and this is more of a question so people who know more can discuss about this (I haven't seen anyone talking about this here)
Some time ago, I got a Theresa and while I was looking at her job advancements, I noticed that Spirit Walker and Witch Doctor look way, way weaker Inquisitor and Archbishop. After seeing that, I went to the Gallery and checked Luthor's and Lucille's job advancements and saw the same thing. This, added to the fact that I've never seen any Spirit Walker or Witch Doctor on PvP (I don't really play PvP that much so this could be incorrect).
I noticed that these two classes focus way more on CC than the others, but the differences still seem way too big.
What do you think? Again, I know nothing about balance and this is only something I thought could be interesting to talk about!
