Hey there!
It sounds like you’re looking for a really supportive and patient environment, and that’s exactly what The Misfits is all about! We’re a small, no-voice (text-only) guild focused on creating a relaxed space where players—especially newer ones—can learn group content without pressure. We love helping each other out and taking things at a comfortable pace.
That said, we might be a bit too small right now for what you’re looking for. We don’t have people online every evening for regular group content just yet, but we are slowly growing, and our short-to-midterm goal is to form M+ groups. If you’re open to a smaller, tight-knit guild that’s still finding its footing, it might be worth checking out our post! You’re also welcome to chat with some of our members to get their first-hand experience and see if it feels like the right fit for you.
No pressure either way—just wanted to reach out. 
Wishing you the best in finding the right guild!
