I'ma european Player, and this is a european server, not a asian one, it would be impossible to adjust tw times for everyone, Aga and the GMs already made it 2 hours later to adjust.
Lets not forget not only DO, but all factions have players from all part of the world that have to adjust, I can tell you that me in my case have to prescind from my saturday go out with friends to come home for TW. And labs fro example have to wake up in middle of the night to come TW. Everyone in NH make sacrificies to attaend TW. We cant just adpat TW times to what ppl would like to.
