Hello! My guild Evolved might be a good fit for you! We are an 18+ community on the Proudmoore server. Most of our members have families, jobs, etc so we understand the importance of real life coming first. Because of this, we do not require 100% raid attendance. We run 3 raid groups, so plenty of room for you and your friends. We also work really hard to make sure friends get to play together on the same raid teams 
Everyone is super friendly, mature, and a ton of fun to be around. We do occasionally towards the end of a raid tier work on Mythic content for a fun challenge, but it is optional and not required for those who prefer to stick only with heroic raiding!

You can contact me at BNet Starlight200#1548 or Discord Star#0700 if you have more questions!
I wish you luck in the guild hunt! Finding the right group makes a huge difference!
