We sound like we may be a good fit for what you are looking for. We are all about that age range, have jobs/kids, so it's more casual. However, we do large yield cq, we do group up a couple times a week for ops/fps, etc. We have a sister pub side guild, full guild ship buffs, discord, etc. Here's a link to our guild recruitment post, and good hunting!
