Lae'zel: Who ever designed her, needs to be fired. Flat out. Because they gave you the absolute worst trope imaginable. The arrogant above it all character. A couple of things to understand about that trope, she is level 1. Which means at best she is a peon. And the things she is fighting have more than a few ways to flay her alive.
All companions have that problem.
"Astarion is a High Elf Rogue who has prowled the night as a vampire spawn for centuries". And in all those centuries he never learned to kill something bigger than a rat? (Level 1) Also, he's arrogant, too.
"Shadowheart was sent on a suicide mission to steal an item of great power." as a level 1 character?
"Wyll made his name as the heroic 'Blade of Frontiers'." as a Level 1 character?
The origin stories are terrible through and through. They're all some kind of super hero, yet when they hit you with a stick, worst it does is tickle you.
If you want to play a normal person, there isn't one origin story for you. There's no butcher's son trying to become a knight. No huntress who was snatched while travelling to her love of life. No monk getting drunk in a bar, when he was taken out of the blue by an Illithid. No mage scholar who got exiled for reading into dark magic or something. Very disappointed.
