Whilst frustrating, these servers are based on PST time zone, so the time of features is decided based around that. Bringing GW time back to WB 1 or 2 will go against that as it will then be within the working day of PST time zone. As inconvenient as this might be (including to me as I am from an EU time zone) I don't think that GW time should be changed.
On the other hand, I do agree that BG could be better planned. Having an hour at it's current time and an hour earlier in the day, but only allow the player to attend either one and not both, would really improve the gaming experience for the majority of players.
Aeria has already approached the devs with a suggestion about BG which was rejected. Unfortunately the devs are refusing to implement anything like this as this is a US server and they do have EU servers open elsewhere.
I am not optimistic about any change happening any time soon.
