Are living learning communities worth searching for a new roomate?

I previously found a roommate through a web service and we agreed to request each other on our forms, but I realized in housing that any requested LLC take precedence over a roomate request. The problem is the person I requested doesn’t fit in with either WISE or Biology house llc that I’m interested in because she was admitted to CLA. She’s willing to put down the same llc as me, but she really has no chance of getting in. After finding someone I fit with, and know I can really live with for the year, I feel really hesitant to start looking for a new roomate that also wants to be in one of the same llc, But at the same time I am unsure if the LLC might give a lot of good opportunities I might not have otherwise. Can anyone share the experience in the LLC’s? Or just give some advice to what my best option might be
