Guild Wars 2

Main solutions would be to not WvW when you can’t get a kill or complete a event. Which on this server is most of the time.
The winning side should have a geometrically more difficult time holding more area. Right now it seems the more keeps you have the easier time you have doing everything. It should made to be near impossible to hold the entire map.

A. You could offer free transfers of spefic guilds off the dominate servers to low rank servers based on there wvw stats. You could retire the dominate server and force a move to others less populated servers.
B. If a server is dominating early in the week, end the match. You could have the dominate server play itself only. It’s side choose by the zone color you enter under. The two losing teams would fight each other or enter into a mid-week compeition with the other losing servers.
C. You could balance by number of players allowed in the zone. Limit the winning (kill/hour) sides numbers and increase the losing sides numbers for the zone. The winning side would have fewer and fewer players.
D. You could balance by de-buffing the winners and buffing the losing side. I prefer this cause the winning side is organized tight guild groups vs the losing sides solo wandering (I’m casually solo and wander).
E. You could add a map icons for the enemy’s having killing streaks like Aion had. The losing side could be able to see all the enemy players dots as red dots on the big map.

The 1 week of being trounced by a better server isn’t fun. If one sides winning badly, conclude the match. Let the winners have the area to themselves for the rest of the week. Setup new matches for the loser for the rest of the week.
