Nah, that's still 11 AM for me and forgot to mention that i usually sleep in on Sundays. I can battle Saturday 8 PM-12 midnight your time (Noon to 4 PM my time). If you can't stay up that late, would 7 AM-9 AM Sunday morning work for you (11 PM-1 AM my time)?
if neither of those two times work, you'll probably just have to stay up a little later on sunday night, like 8-9PM, which is when I will be waking up, noon-1 PM my time.
5-7 PM for you is 9-11 AM for me, and i have class around that time most days of the week. I think the best way to go is to play this Saturday or Sunday. What time works best for you then? I can play pretty much any time during those two days.
