Greetings Dramen,
My guild The Twilight Tier (H, Saurfang) is currently recruiting players after a time of inactivity. Those of us who are active are 30+ and our active times are generally as those you described.
Our main focus right now is building a community where everyone feels welcome and at home. A place to chat amongst like-minded players after a long day, and relax leveling an alt or doing dungeon runs.
Although I cannot promise you that we’ll reach Mythic tier raiding, as it’s still early days in the guilds revival, it’s not an impossibility. Regardless, know that you are more than welcome to join us.
If you’re interested, feel free to DM me on Discord (Veletala#8483) and I’ll be more than happy to answer any questions you might have.
