This is a casual player quality of life change, nothing real important, but one that could probably be implemented fairly easily…
As it stands right now WvW resets on Friday evening, brining all of the server bonuses back to nothing for the weekend — the time that casual players are able to participate in game play the most. If the reset were to take place on Sunday evening instead of Friday evening the WvW bonuses would be more effective for most of the players. It might even cause some casual players to care more about WvW and fight for their home servers for a few hours at reset.
