I don’t know what is the best solution for wvw servers and server matching. Something major has to be done, but Anet has been shown even the smallest changes can have a deleterious effect. This proposed change is so global that the consequences of it would be hard to determine, especially when the smallest detail could derail the entire thing.
I assume Anet won’t share its ideas/plans for the wvw overhaul before they are rolled out. This makes evaluating the relative merits of Anet’s plan and this plan impossible. It would be nice if Anet’s wvw team commented about this and wvw in general.
