It would also help if instead of making memes and daydreaming about the companions people would instead more loudly complain about the unfinished state of act 3 and bad story/ending which would force Larian to do something to save their reputation.
But as long as there are people who constantly shout down any criticism of BG3 and instead flood channels with their Astarion fanfics nothing will happen.
Don't think thats true actually. From what I've seen plenty of people are complaining quite vociferously about the unfinished state of the ending, the lack of anything which shows how our decisions affected the world (Larion need to reinstate the 6 month after party maybe) and the lack of proper companion endings. Larion did more for Karlach due to Karlach fans kicking up a storm but the other companions are treated just as badly. Asterion fans are complaining about it just as much as anyone else given his ending can be completely bugged unless you kill another well liked character and even then can be pretty awful due to a sick joke, and the other companions aren't much better being cut so short as to be almost unnoticeable. But I certainly have noticed plenty of threads complaining about both issues - maybe one of the moderators on the forum needs to amalgamate these threads a bit but that would be a difficult task to undertake.
