I'm thinking more like 16 man teams. Trying to field 24+, even in many guilds would be difficult at best.
And yeah, FPS could be an issue. I know the BW team has a lot of work cut out for them. I'm not even thinking this could/should be something that happens soon. Maybe around the 9month or 1 year mark would be good. I just want the opportunity to queue with more of my guildmates and have some multiple objective based, larger (not huge mind you, not yet) scenarios.
Something a little more exciting than Cap two and win, or pass, stun, pass, stun, pass pass win.
