The new chat channel feels like an immense waste of time and effort to me. Instead of putting in the effort to build a new global chat channel that is very unlikely to be used the way you are hoping it will be used, I think it would be a far greater benefit for newbies/returnees if you raise the membership cap on Linkshells.
Only 64 online members just isn't enough room.
If the member cap were raised to something crazy like 1024, there would be no need for this new channel on Asura because my linkshell would be recruiting every new/returnee player on the server as soon as we can find them. More realistically, a bump to 128+ would be greatly appreciated and let FaceDesk get back to our core mission of turning FFXI newbies into vets.
