Perhaps dividing GW2 servers to NA & EU zones was not a good idea concerning 3W. The daily circle gives western players advantage because they can hold map while sleeping break.
So worldwide spreading maybe more useful, but the west coast will have last word because of low quantity Far East players.
For bringing the situation to more reasonable state I suggest the following.
Every death on 3W fields even from falling substracts 1 point from server score. It is a good tool for ranking more skilled teams and prevents the “scatter corpses” tactics.
