Hey there! I think we might be exactly what you’re after, we’re also primarily filled up with older raiders who don’t have the time or don’t want to hardcore raid anymore. We push as far as we can into Mythic but we keep it relaxed and chilled out, with no toxicity/raging/screeching/etc. We’re also open to cross-faction raiding if you prefer to stick Horde. 
I’ll hit you up on Discord but I also wanted to leave more of our info below, good luck on your search regardless! 
For a very brief TLDR: 7:30-10:30pm EST Tues & Weds, mainly filled up with older raiders, no drama, chill vibes, 9/9H & 3/9M before we took our raid break for the tier!

Chaotic Neutral is a long-established semi-hardcore guild located on Alliance Turalyon that has been around since TBC! While we aren’t a hardcore CE push guild we do like to push as far as we can into mythic with a relaxed and chill raid environment, we’re a guild that prefers to have fun than get angry about progress.
We raid Tues/Weds from 7:30-10:30 pm EST with an optional Saturday extra prog/alt night in the same time frame if we have the people. If you’d like more info on our previous progress please visit our WoWProg page, for our loot rules please visit our forum post. All we ask of raiders is to research fights and research your own class so you can play to the best of your ability!
We were 9/9H & 3/9M Aberrus before our break.
We also have members who love running all levels of keys, and would be happy to bring more people along!
I’ll leave all our additional info below that I recommend checking out, but if you’re interested then please add my btag or discord to get in contact or put in an app on our guild site, hope to hear from you and if not then good luck on your search!
