I would be very much in favour of a shaman base class. I created a shaman-like character using a celestial warlock chassis, but I felt if fell short of my character concept in a couple of key areas.
* I conceived my character as wise, rather than charismatic;
* Too much emphasis on Eldritch Blast, too little support for my totem animal (Bear).
In addition, if the latest contributions are anything to go by WotC are running out of sensible things to do with subclasses, adding more base classes would be a better way to continue to add new player options.
That's what I did, but it didn't really give me the character I wanted - you can't play a grumpy curmudgeon with a Charisma of 16, and you can't get away from zapping energy beams from your fingertips without gimping yourself.Alternatively, what's stopping your Warlock from making Wis their second highest stat after Charisma, and investing in some Wisdom-based feats/features like Magic Initiate (Druid)?
It's a strawman argument anyway - shamanism is one of the most widespread belief systems on the planet, no single culture or ethnicity can lay claim to it.Xanathar's has a sidebar on this topic about "samurai" and "cavaliers". Short version: it should strive to be respectful, which isn't necessarily the same thing as accurate.
