You're right in my initial comment I didn't say "I would use this," but that's because I personally stated the option I would find the most enjoyable to use (a fifth option that goes for required roommates with player's choice of randomization or personal choice of roomie). I figured my stance was obvious since I'm promoting the roommate options.

I did state it directly in the comment to Li above yours, too, but yes I would jump on the roommate options. I think it's a great way to build CR and we need more options open that make it logical for characters that wouldn't normally interact to get to know one another, beyond "they walked past each other on the street."
