Hello! My guild Evolved might be a good fit for you! We are an 18+ community and 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 multiple raid groups, so plenty of room for you! Everyone is super friendly, mature, and a ton of fun to be around. 
We like to focus on having a strong community as it makes the game so much more enjoyable! We do all kinds of things besides raiding such as M+, arena, world pvp, dungeons, etc. We just like having fun together! 
Evolved is an Alliance guild on the Proudmoore server. We are a raiding guild, but that isn’t just what we do! We of course do not require our members to raid to join us and we have plenty of members who are more casual and enjoy doing all the other aspects of the game besides raiding! We do offer a no commitment required open raid on Sundays that might work well for you if you want to try a more casual raid when your schedule allows it!
