Greetings, Smopes!
Vigilant is an Alliance Guild on Sargeras, We have two teams, both teams having cleared Mythic in past tiers. I am specifically representing the weekend team which raids Sat/Sun 8-11PM CST. We are seeking skilled players such as yourself so that we can continue to push our team towards cutting edge in a fun, more laid back but still structured environment. I have included our forum post below with more information, including our guild website.
We run a lot of Mythic Pluses and have a very active community . Best of luck in you search!
Remain ever Vigilant,
Unholy
