Although nerfs seem to hurt, they don’t outright kill the class.
HOWEVER, with these nerfs comes perception of a nerfed and weakened class. This downfall of a class-image will probably hurt us in coming expansion far more than one can expect.
Just look at the shaman example in BFA.
Shamans in the end were quite OK but the perception was so bad that noone wanted shaman in group nearly in any content.
My biggest concern currently is that DHs will become the new “shaman”.
