That's the exclusivity thing. Not every company has millions of gil to throw away paying greedy people to do us a favor. Having this lockout helps no one and it doesn't stop companies from doing this as a group project if they choose to. The fact is, small companies exist. "Full or Light party required to proceed" is the most annoying, useless thing they could have done with this. Yeah, I'd love to make new friends. But I'm on a weird schedule as is, I don't do raids and extremes, and most of my time is only spent with my company. TL;DR, companies who can and choose to can easily maintain that company activity, but those who can't shouldn't be forced to rely on strangers who don't /actually/ want to help in the first place.
