Hi Tristaris,
If you are still looking, may I throw my hat in for options? My guild may have what you are looking for! We are currently rebuilding after a long hiatus, and while we do aim to have a raid team ( no pressure to join at all) we will have a focus on mythic plus, as well as some casual PvP.
I will leave a link below of my forum post, for you to look over, and if you are interested, feel free to reach out!
