Yes, please! I've hoped for it every single patch this year and I've yet to see it happen. I would love for it to increase to 128 members, maybe even more since it's meant to contain people from more than one world (and even data center, now)!
It would help with CWLS for The Hunt content so much. I would be able to add more people who could attend these hunts and more people who can relay when they've found or spawned a hunt. That would help console players so much. It gets rough to play on a console and rely on someone's late linkshell relay because it came through their cross-world linkshells late due to size limitations (being unable to invite all active spawners). All of my CWLS are hunt-related, and they're all filled to the brim with more people constantly seeking an invite than there are invites to hand out.
Speaking of more people wanting a CWLS invite than I have spaces in my CWLS, it would be great if they could add some sort of way for me to see when people are inactive or haven't played since the last maintenance or something. I likely have people in my hunt CWLS that haven't played since before 6.1, but I have no way of knowing without kicking them, which could mean I accidentally kick someone who was active mere minutes ago. I just want people to come join hunts! They're so much fun and the recent expac's hunts are very helpful to people who need to cap for raid within a short amount of time because of real life commitments.
It would help other kinds of CWLS, too! I would be able to merge my current hunt CWLS and finally join a CWLS just for friends or raiding or anything. 64 can be so small when it comes to these things.
