I thought you expected a reply.
I agree with Necromancers.Yes. Yes, it can. I'm someone who strongly prefers an actual class than "class skin", but even I can admit that reskinning classes can bring other fantasies fully into realization. A reskinned warlock class can fulfill the necromancer fantasy, as much I would prefer the concept to be its own class with its own unique mechanics. Sam thing with druids and tinkers, hunters and dark rangers, warriors and barbarians/blademasters, etc.
I'm not allowed to comment on the "Big Bad class", so i'm just gonna .
As for Dark Rangers and Blademasters, this is not the case.
