I stop liking a lot of art because there is a human in it but still that doesn't entitle me to complain about it publicly or in dms because it is not my exact preferences

I was specifically refering to mechanics since bg3 is adapting the mechanics but yes there is that aspect of a sentient weapon patron that is good and interesting flavor specially for the dm to play around with but in the actual subclass nothing would change if your patron was a ring for example

I have played and read hexbladr many times on the time I've spent on tabletop and I can assure you the actual 5e hexblade was just a warlock with charisma to melee, curse and invocations to support it, idk about the onednd if there is one but that would be irrelevant since bg3 is based on 5e

What? Not really, there is no special focus on some sort of specific weapon or feature aside from the profiency, charisma to attacks and the curse itself that they already improved by giving you a chance to apply it at random. Only thing they did was expand a throwaway feature from level 6 on 5e

That's not raise dead that is accursed specter which is a feature on tabletop about making the souls of your enemies bound to you and they are adding a lot of variants for it

Congrats
