Not sure if you can raid an extra 30 minutes or not.
We’re a new guild so we kinda need the extra time to play catch up and recently added a third day. I think this was our 3rd week of Mythic raiding (we did H EP and H Nya the first week we had people after setting the roster in a week) and are 6/12M.
Schedule is T/W/Th 8pm-11pm EST (7pm-10pm CST)
We do optional M Jaina runs for people who need mounts (in or outside the guild) on Saturdays on my recruiting discord.
