Do not fucking implement that shit.
Bring necromancers and get it over with. Any argument in opposition is purely subjective and backed by nothing but your beliefs.
Demon Hunters have proven that it’s possible. Blizzard’s stripping of Demonology to create the Demon Hunter class was simply terrible economization of resources. Blizzard successfully TINA’ed the mindset of the player-base.
Stop fucking with us. Implement them.
