Hey there! We may be just what you are looking for! We are currently 6/9H. We are definitely a mature guild…all adults and several of us are on the west coast 
We raid “late night” Wed/Thu from 11pm-1am server time. We do weekly keys and are in discord pretty much every evening! Would love to have ya join us… here is a link to our post! https://us.forums.blizzard.com/en/wow/t/h-alt-tab-conspiracy-late-night-raiding-guild-9-9n-6-9h/84140?u=deathblooms-thrall
