Everyone is fixated on my feelings while completely ignoring that I back them up with actual arguments. You all just reduce it to "just because you don't like it doesn't mean others don't" while I'm out here explaining what's wrong with the characters and why they're unlikable.
I provided several arguments in other posts and also a five paragraph accounting of my experience with Shadowheart in my first first playthrough providing arguments and motivations, you just either didn't read these things or chose to ignore it because they're not in line with your own opinion. I literally quoted you saying that no one explains why they like them based on their emotions and then provided an answer why I like Shadowheart based on my emotions when playing through the game.
Concerning the rest, I'd mostly just be echoing Taril at this point, so I'll just say I agree with pretty much everything he said.
When it comes to specific companions, I'm less negative about Astarion and Gale. A main point of critique for me is probably how Wyll doesn't have a Nightsong point system of sorts that allows him to choose on his own whether or not he prioritizes his dad or his soul. I find that if you save his soul and then find and save his dad, he does have agency whether or not he stays under his dad's wing or become the Blade of Avernus, but with the biggest choice of his quest, it's a very weird writing choice that he's not able to decide for himself. It's also rather game-breaking narratively that if you go straight from the coronation to the Iron Throne you will find Ravengard dead in his cell, but if you have a Long Rest and Mizora's contract choice, Ravengard will then be alive in the Iron Throne if you choose to save Wyll's soul. It makes zero sense the way things are currently set up chronologically. Aside from that, I do like Wyll even if I find him a little preachy and a bit holier-than-thou.
Also, Karlach's act 3 part of the story feels largely unfinished. Depending on choices, Dammon will be in act 3. You will also continue to find infernal iron and even enriched infernal iron. Enriched infernal iron in particular is an item that seems like it should have had a special use considering Karlach's earlier quest steps and Dammon's interest in infernal materials to forge stuff with, but it's entirely useless. Her character arc is tragic, but with the things available to you in act 3 it feels as if her engine should have been fixable as long you kept Dammon alive and found the necessary materials in the Steel Watch Foundry.
