Another simple, straight forward suggestion.
I prefer to WvW with my guild (crazy, right?) but short of sending whispers to every member who is in WvW to ask which zone they are in I have no way of knowing which zone to join.
This problem is exacerbated in a big way when WvW queue times are introduced because it then requires members to coordinate the zone ahead of time. Often I’ve found that people are reluctant to hassle a bunch of members for their zone info and instead default queue for Eternal BG. This overpopulates EBG and makes the other zones less appealing.
