I played with the DK and Druid trees and I like what I see.
So then I decided to put a class and shadow tree together.
With the way I did it, not only does the shadow priest have like every cool ability we have had at some point in the history of the spec, but I also managed to put at least 3 and maybe arguably 5 different distinct play styles on the same tree.
Priest Shadow spec tree…
Priest class tree…
