Everyone is complaining about that weapon should have belonged to Shaman or Paladin but I can see the connection with the hunter honestly and liked it.
Dwarven Gryphon Riders uses hammers most of the time and they all are like hunters more than paladins/shamans so I liked the flavor here.
Look how they themed hunter in this expansion around Gryphons/Riders/Dwarves and Primordial Dragons. I think it fits well and I have been playing hunter for a while in past. Also this Stormhammer is a ranged weapon with lightning power of it.
The term "Hunter" doesn't mean Ranger tho.
See Falstad Wildhammer for example. He is a Gryphon Rider and using a weapon like it.
I liked the flavor of it tbh.
I can leave now.
