I don’t think there are any decently progressed mythic morning guilds that raid that schedule… you might want to try Oceanic TBH.
That said, if later morning times might work here’s our spam 
We’re a daytime Mythic guild previously on Sargeras (Alliance) who have decided to make the swap to Horde on Area 52 for Shadowlands. We are looking to enhance our roster with skilled and reliable players.
Our group is one of friends, who push each other towards excellence in game while maintaining a healthy sense of humor, open lines of communication, and clear sense of direction. We are a level-headed bunch, hungry for progress. We have a low tolerance for drama and do our best to foster a positive in-game environment.
Swell’s core is composed of veteran raiders. Some of us have been playing together for years, and some of us are new friends. We have a solid foundation for our dream team – we’re searching for a few more to help round us out!
Currently, our main search is for competent, hard hitting DPS. As we move into the tail end of the expansion, we are looking to relax after earning CE and build our roster for the upcoming (and exciting) changes in Shadowlands (read: our new team is now 10/12M but we do plan on getting CE again this tier). We normally maintain a 25-30 person roster to flex for boss requirements and schedule changes.
Swell has historically fielded a bunch of key pushers, and we work together to get everyone a key completed every week, and we have interest in rated BGs, world PvP, transmog and achievement runs. Alts, casuals, socials, friends, and families are always welcome!
[H] <Swell> 12/12M 12/12H NYA [8/8M CE 8/8H TEP]
Raid Times: 10AM-1PM EST/Server | Wednesday/Thursday/Friday
Monday/Tuesday are sometimes OPTIONAL flex days early in the tier, but we generally have Heroic sales Tuesday at reset (11am CST) during active raiding seasons.
** Note: We are primarily looking for DPS, but we will consider any exceptional talent. **

Requirements
Mythic raiding experienced is absolutely required. We have mandatory addons and WeakAuras that we expect all raiders to use. Discord is required, and a working mic is necessary.
Attendance
We are a guild of dedicated and ambitious players. Commitment to our raid times is mandatory. We’re interested in consistent players who are realistic and honest about their day-to-day schedule. Raiders are required to communicate any tardiness or absences via a Discord channel or through tells with an Officer. Schedules change, things come up and real life always comes first. All we ask for is a heads up!
Trial Period
Two weeks from start date or six consecutive days demonstrating attendance and competent play. Start date begins on the first raid day you are present. Trials are always given a feedback session at the end of their trial period and we encourage you to talk with us during and before this about anything and everything.
What you can expect from us:
- Dedicated leadership.
- Effective communication.
- Well defined goals.
- A sense of community.
- Good attitudes.
- Honest and helpful feedback.
- Raid materials (Vantus Runes, feasts, cauldrons).
Our Officers are always available to speak with, and we expect our raiders to help us maintain open lines of communication about their needs and concerns.
What we expect from you:
- 90% Attendance rate, as well as being on time (early).
- Excellent communication skills.
- Survivability and understanding of mechanics while excelling at your role.
Many players struggle to do one - we are looking for both.
- Ability to introspect regarding your play in order to be constantly improving.
- Willingness to integrate yourself in our community, as you are comfortable.
If we sound like a good fit, let us know! Apply via Guilds of WoW, then reply here, or send us a tell on BNET/Discord. Or you can go old school and send in-game mail to Khavá, Kalanee, or Foxicopter! Thanks for checking us out and we hope to see you in gchat soon.
