This has probably been said here already, but the more I think about it, the more I realize how tacked on a lot of her story feels. Her big quest objective (kill Gortash) is already an objective of the main story. It's literally something you were already going to do anyway. In fact, you have to do it if you want to progress in the game.

I don't know.

I was really enjoying this game, enough to play through it 4 times back to back, but the 4th one (where I focused on Karlach) just felt so unsatisfying. I'm kind of just feeling empty about the whole thing now. I think I'm going to put the game down for a few months and hope things get better.
