Without spoiling too much, there is quite a bit of payoff for sticking with Lae'Zel until the end, imho. I do agree that she is a bit off-putting at the start, though. Unfortunately, I didn't get much time with Wyll or Karlach, which is a shame since they seemed like some of the more enjoyable companions.

I'm also bisexual, and frankly, I'm not a picky eater, so some character quirks don't really stop me from having a good time. (I do understand that some people have more specific tastes or higher standards, and there's nothing wrong with that.)
