As a FS player it’s clear that VS is simply more organized. No matter what map I join for WvW I find people AFK at the spawns. The people who do play are split between exploring (gotta get those vistas) and not knowing what to do.
Luckily we have plenty of people who do know what to do. These people spend their time in /map and /team to tell the others they’re doing it wrong. Very rarely do I see anybody step up and take control.
The FS players tend to be very unorganized and rarely listen or talk in the chat. I think a lot of this will change when more people get their desired Exotic gear and only have WvWvW left as a gold sink.
Edit: Kudos to VS for getting your people and guilds so organized.
