Hi Hawksby,
come and check us out. We are a raiding guild with the focus of at least getting AOTC, and pushing further where we can.
Many in the guild also get together to run mythic plus. Pushing for Keystone Master and Hero.
I will share a story of one of my first mythic plus runs with the guild, up to this point I had been pugging practicing to join them in 20s later in the future. They pulled me into a 16 I had only ever done 9s at this point and I was the healer.
We finished the key eventually 
, had a laugh every time a person died or got hit my a mechanic, we didn’t give up and kept pushing forward. Finally getting and downing the last boss. I kept joining them each week getting better and eventually timing 20s and higher. Memories I wont forget.
