Hi there. I run a casual raiding/social guild that may meet your requirements.
We run raids twice a week, although one of those IS in a Friday, although our main night is Wednesday.
We have members that run M+ and we currently have a “Mythic Monday” scheme where people get together and run no pressure low level M+ with no pressure to time, just to learn tactics, routes, etc.
We only run Normal and Heroic raids.
You can learn more about us via my word wall! (sorry about that )
