The WCA should add a "continental rotation" system, like a 6-years cycle with 2 worlds being either Europe, North America or Asia, and the remaining one being either South America, Africa and Oceania. That may seem strange, but advantaging north-hemisphere-continents is justified by the fact that there are more people, more cubers, more infrastructure and accessibility. A place ticket from North America or Europe to Australia is very, very costly and the times zones lag can hurt performances. Also, it's not as harsh as what the WSSA does!
What do you think of that continental rotation system?
