Seems too similar to typical Hunters. It’s specially bad since both classes already have “hunter” on the same. Idk, if DHs are to be ranged or have a more flexible toolkit, it should be through spells, not arrow. Might fit better as talents or even a 4th spec for Hunters.
When it comes to 3rd specs, I’d go with one of these two.
I was thinking about a 3rd DPS spec with some support heal through leech and other effects. Basically, a Dreadlord spec with Vampiric Aura to suck the life out of your targets to heal you or your allies. Meant to have more ranged spells and some stealthy utility.
If you think ranged playstyle is more interesting, I’d say a Spellbreaker concept fits the class a lot more than “hunter with fel arrow”. They wield glaives and manipulate/counter magic, similar to what DHs already do, with one detail being Spellbreakers are ranged. It’s Blood Elf in origin.
