I recall SWTOR raids always ending before 10 MST. I wouldn’t go all crazy thinking you have to leave guild for something else at this time because who knows what we’re going to do yet guys…there is 20 and 40 man content to think about scheduling. Ideally that would mean having 2x 20 man teams and maybe 1 teams is the night owls and the other is more for EST players and then we meet in the middle for 40 man…who knows just yet.
I live in South Carolina and raided with Afterlife in Rift. Most raiding nights, we would start around 8 or 9 pm and finish around 11:30 or 12. It was pretty manageable for me. I hope you will find it to be the same.
I’m up in New York, so the PST is a bit of a concern, but I knew what I was getting into. I should be available most nights as of now, up till about 11-12PST at the absolute latest.
