Guild Wars 2 World vs. World players, take note: ArenaNet is changing the time that it resets the matches. According to a quick post on the forums, the time is changing from 8:00 p.m. EDT on Fridays to 6:00 p.m. EDT. This was done to balance convenience between North American and European players, although west coast players have pointed out that the reset change makes it decidedly inconvenient for them. The new reset time goes into effect this Friday.
