Heya Winstor. I run an Alliance guild that might be close to what you’re looking for. We’re pretty close-knit, skew older, and put emphasis on liking who we raid with above most other things. We do still manage to get things done, typically clearing Heroic in time to get AotC, and we have raiders from lots of different backgrounds and experience levels.
We are pretty small, so there aren’t tons of people online at all hours, but we use Discord and you can always find people around there who can log on and do stuff. Here’s our recruitment post for more info, or you can contact me (ennui#1686):
