Thanks for the quick response.
Unfortunately Kallipssa, 1:30 pm server on Sunday is 7:30 am on Monday so is not a time I can make it. This is why I was asking about the early morning times - I have seen quite a few guilded players on at this time so was optimistic there would be a chance at these times. Although I understand this is outside your normal raid/boost times, hence my caveat at the start.
