I am sure I will receive a ton of flak by Larian fanboys for this and that's fine, I haven't played the full game only early access but I am hoping the characters actually have some degree of character development.
Fair, just like the rest of us here.
As it stands, I hate all of them they are all full of themselves to a narcissistic degree, some of them are outright the most unrelatable abrasive lunatics I have ever had the misfortune of encountering, other than her strength and her saving you (more for herself than you) Lae' Zel is utterly unlikeable.
She fights you on everything, is never satisfied and even when you do something that pleases her she tells you in the most condescending, arrogant, annoying way possible, the only way I know she liked my action is because it says "approves" in the top left hand corner, otherwise half the time I would have guessed I screwed up.
Every RPG has that companion. In Dargon Age there was Morrigan, in BG2 we had Edwin, in Neverwnter Nights 2 there was Bishop. Probably a lot more.
All of the characters are hyper defensive and you aren't allowed to even ask questions of the people that are laying close enough to you to kill you in your sleep, lest they start insulting you and becoming verbally abusive.
Think we played a different game? Name one such situation, I don't recall anyone becoming "verbally abusive".
All of the women save Karlach are utter bitches who seem like they are actively putting in effort to make sure you never use them with how much they berate and verbally abuse you, and all of the men save Halsin are clowns I don't take seriously at all.
Oh, so no girlie has gone "you are so handsome Senpai!" on meeting you and the guys won't invite you for beer and it makes you sad?

Also, again, when exactly did anyone verbally abuse you? Tell me where it hurts.
I thoroughly enjoyed romancing Viconia from BG I-II, even evil you saw a lot of character development with her, could even turn her around to being a good guy, if you played your cards right.
And yet she was "verbally abusive" from the start, lied to you, used you, and yet in the end she became the perfect waifu so all is forgiven, yes? Yet you don't seem to want to extand the same courtesy to Lae'zel or Shadowheart? Why?
I am sure I am being theatrical [...]
You are.
Before anyone would say "the characters are complex you can't just say the right things and they like you."
No they aren't complex at all, I can't get anything out of Minthara, Lae' Zel or Shadowheart but utter bitch no matter how high my approval is, they always talk to me like I am garbage or their slave
How can you tell? Didn't you just say you haven't played the whole game yet? Shadowheart ended the EA pretty friendly with all my characters, so... maybe it's just you?
The males I can't get anything but jokes and deflections, I barely know who they really are because they don't want me to, since all of the females are probably evil aligned I guess I get it, but there isn't a soul on earth that likes being treated like shit in a friendship or relationship so they can go die by themselves for all I care.
Do YOU spell out all your secrets to strangers? Get to know them, all of them end the EA telling you at least a decend chunk of their secrets. If you, you know, talk to them and be nice.
To be clear, anyone who wants to reply with things like "you are stupid you don't know what you are talking about."
Yeah I hope so, I am praying so, please come correct me, please come tell me how dumb I am, and that I am wrong, I desperately want to be.
I won't, no matter how much you ask, because I'm nice!
But you probably are wrong.
