How about once a year there have a Guild v Guild v Guild tournament. Guilds or even group of guilds can form 40 man teams and spend a certain amount of time fighting it out in EB. I am thinking 6 or 12 hours time periods. This would give smaller guilds a chance and eliminate off-hour capping. Do it once a day on the weekends till there is only one guild standing. Have different brackets based on where you live. People can sign-up based on time zones. Once you start getting into the semi-finals and stuff, you would have to come up with some sort of timezone compromise.
Basically a GW2 March Madness…..
Be interesting to see how guilds really stack up. I am willing to bet the landscape would be totally different from the WvWvW landscape.
