Generally I definitely agree with you. Specifically about what the community's priorities should be when providing feedback about the game. I have seen many complaints about general gameplay that even if Larian will never address, it would be modded into the game sooner or later (and if you take a short look at the mods that already exist even now you'll see it's probably sooner).
I'm much more worried about story and characters right now as well. However, i don't necessarily agree with all your points. I do think companions who are possibly the main character are a problem, but based on the popularity of the feature I doubt it's about to change. The characters themselves are good, and I'm not sure introduction is as important as you make it to be.
