You can call Neverwinter whatever you want still is based on 4e.
Like Sword Coast LEgends is """based""" on 5e but has almost no things from the source material on it. DDO which already has a huge problem with number inflation and cooldowns is far more akin to the original neverwinter(1991) than this generic wow clone.
Honestly i dont think i would buy any DLC that brings only "another class" ... even less if that class is only alterned, or upgraded version of allready existing one. :-/
Maybe just as part of some kind of season pass.
Thanks for the answer.
I asked this because honestly, necromancy is extremely lackluster on 5e. And if Larian implements a single summon limit, why not just remove the class?
