Time zone is out of blizzard's control. Even if they did a global wide release of the raid. One region is always going to have an advantage due to being able to raid during the day versus having to raid into late nights.
Also an official competition cannot be taken seriously if ever raid there are always bug/hotfixes when its live.
I haven't been able to watch as of late, is Za'qul looking like another Mythrax or another Avatar?
The intricacies of running a world first guild, interesting read! I can't give enough props to Method's leadership over the years.
