Hey Ðrac!
I’m sorry to hear that your guild quit raiding! I can understand how that feels - my last guild was my home for two years and we kinda of just fell apart and it was hard to find a new place in wow. I joined Safe Word (Kilrogg) and we are pretty awesome. 
We would love to have you join us!
We currently have two raid groups, raiding Tues & Thurs, Wed & Mon, 9-12 central time. We’re currently recruiting for our Wed & Mon team, which is our heroic progression group. This group is preparing to dig into mythic in the near future so I think you’d fit in great there! I would definitely say we are relaxed but also want to get stuff done - know mechanics, know your role, etc. We also do quite a bit of m+ and pvp stuffs if you’re interested in things outside of raid.
Here’s our main recruitment post for more specific info:
My bnet is Lyra#11630, disc is Esaora#3578. Hope to hear from you soon!
