At the moment my time in Warhammer has been limited. I am still playing I have a Shaman who I am comparing against my Zealot.
I find him more amenable. His starter zone is better and he has a touch of the comical about him. Early on his mechanic seems more interesting, and reading on the forums the views tend to be positive about them later on. With posts like 'I love my Shaman'. Which I think is a first for a MMO class.
