Our raid times vary based on the group. We have 3 groups running at the moment 1 does mondays/tuesdays 7pm est to 10pm est while the other two groups run 8pm est to 11:30 but one is weekdays and the other is weekends. When 2.1 launches we will be working with all groups to try and find the most common ground for Crystal Tower but till then the BCoB groups are built then they talk amongst themselves and decide when everyone can go.
