Hey Frostycake! I think our guild might be what you’re looking for! We are a Heroic/Mythic raiding guild so I do understand that might not be exactly the best fit but with some time we will have you getting involved if that’s what your goals are!
We raid Tuesday/Wednesday/Sunday 11pm-2am EST. We have people running keys most nights, including after raid so there are definitely a few of us who are very much night owls. Our guild Discord is active most days and there are a number of people you’d be able to make friends with on your schedule. You can get in touch with me on Discord if you wanna chat: lonesoldier09#0009
And you can see more on our forum post here too:
