Hiya!
I’m with Mediocrity, a newly formed guild on Thrall-US. We’re currently recruiting all classes/specs to build out our guild and put together a Mythic raid team.
For Eternal Palace, we’re anticipating to finish somewhere around 5-6/8M (we can dunk an easy 3/8M on PUG nights, and our leads have 4/8M) and we’re planning on pushing for CE in 8.3.
The only potential concern is running as a DH tank for raiding - unless reworks are happening in 8.3, they aren’t an overly strong option for Mythic progression. If you have a DPS OS we would happily take you on. 
We run Heroic EP clears and M+ keys regularly, and we would be happy to be your new home!
Here’s our forum recruitment post - if we seem like a potential fit, don’t hesitate to reach out!
