Hello Koyvoo!
Stardust is currently 9/10H in CN with P3 progress on Sire Denathrius, so our progression is very close to yours. We raid a light 5 hours a week, and intend to start Mythic progression as soon as we finish with Denathrius. We intend to progress through Mythic each tier, although not necessarily CE focused.
You can view our main recruitment post on the Stormrage forums here:
One of our raid nights is Sunday night, but if you can be flexible with that then it may not be an issue. We are currently looking for a rogue, but also ranged DPS (which includes both hunter and spriest!)
Hopefully this sounds interesting to you. If you’d like to discuss more, please add me to battlenet
