edit - well, fucked up that title, hopefully the rest of the thread goes better. Should be 'just a cool one'
I like Demon Hunters. I haven't played one beyond the starting experience, but they were definitely fun and cool there and I'm sure they are in content beyond. I like seeing them, jumping around and turning into demons and such.
But I'm wondering, did Demon Hunters fulfill some role that was needed before they were introduced? Or was the addition of the class just for the sake of greater variety and because it was thematically appropriate for Legion, rather than out of gameplay necessity? Are mobile jumping demon tank-fighters necessary or are they just rad, something new to experience?
Either way I think it's a good thing to have them in the game, I'm just curious as to whether it can be argued that future classes could be introduced purely because it's fun and cool to have them, rather then so some vital absence in the class roster can be resolved.
