I do not need to bang Halsin (... although ...).
I do. ( ͡° ͜ʖ ͡°)
I agree that I would like a larger party size. Regarding locked companions after Act I... I feel like we really can't say whether this is bad or not until we have a sense for what's planned. It could result in something really interesting and perhaps tighter storytelling which I would ultimately prefer to having access to all companions. In all likelihood, you're probably right and it will be overly limiting. But, I'm personally too curious about what it might mean for the story to pass judgement just yet.
If it's arbitrary that's bs though.
