I think the only true way to solve the time issue would be to have 2-3 Gst's instead of just 1. Some how I don't think the admins would go for that. They probably wouldn't want 4-6 gst winners instead of just the two. I would't really see the harm in expanding the gst into 2 tournaments based in different time frames to accommodate players tho.

Just have a 2nd tournament 3-4 hours before or after the current one. Any guild leader would be able to choose the time frame they want their team to compete in when they submit there team. If there is an lopsided amount in one tournament then the other there could be a global pm asking guild leads to switch their time frame prefrence so it stays even.

Guilds would only be allowed to register for and compete in one of the two time frames. All guild leaders would be asked to keep there time frame preference quiet so nobody knows which teams will be in which tournament. I think it would be best if ppl didn't know when the stronger spar guilds where competing. I just figure if ppl knew which tournament US was sparring in they would choose the other one so they can have an actual chance at winning.
