Ello there! 
We might be smaller than what you’re looking for, but for us, the social aspect comes first! And hey, the age range is a great fit too. We’re a no-voice-chat guild that communicates only through writing in English. Our short-to-midterm goal is to form an M+ group or two, and in the long run, maybe try some fun, casual raiding—nothing competitive or AotC-focused.
Just wanted to drop these lines so you can check out our post and see if it feels like a good fit.
Wishing you the best in finding your new home.
