Hey friend!
I read this and wanted to share the small guild I represent! I have a few players who are in a state of learning the game not unlike yourself! We have players of all levels and understanding, always eager to help and coach! Please feel free to look my post over? I will link it here: https://us.forums.blizzard.com/en/wow/t/looking-for-a-casual-communiity-to-help-build-into-a-raid-team/1911294
If this feels like it may be a good fit for you, please feel free to reach out to me utilizing my Discord information in that post?
Good luck in your search to find the right home in WoW!!!
