Hello Itzexit,
I am a returning player. I came back last spring. Apparently it had been 7 years since I was last online! I have really enjoyed WoW since then but one of the things I was missing was the social aspect of a Guild. I joined a guild for this xpac that I am very happy with at Tryhardish.
There is a wide variety of experience levels that lead to a more casual atmosphere. But, the officer team is knowledgeable and skilled while being dedicated to forming a positive environment. Avg age is probably in the mid 30s with a ton of working adults that want to game.
We were focused on recruiting for a normal raid team recently and now have one going. Right now, a second tank for our AOTC team is a need! We are just getting started after piecing together a crew from our normal raids. I dont see mythic raiding in our future, but who knows.
Other then that, there is a handful of skilled players looking to run keys and also another group of players interested to start. I fall into that second category :). We normally have one or two M+ teams rolling around in an average night as long as its not raid night. Discord is active!
If that sounds like it might be a good fit for you, I invite you to check them out. Cheers,
