Hey Felzug,
Welcome to WrA and welcome to the world of roleplay. There are many guilds that are right up your alley, but I personally can’t speak for them on what times they operate. Since a majority of folks operate on EST and CT (relative to server time which would be PST). 8PM PST is pretty late.
Be sure to check out WrA Information & Directories (Guilds | Communities | Events) the directory and peruse around a bit, maybe help narrow your search. I’ll ask around with some of the west coast people I know on WrA and see if I can find any additional information.
I’d check out Firebrand Enterprises - they’re a rather chill bunch. I’ll also post my own link here in case you’ve got an itch for some Horde-specific roleplay. The Vol'kar Legion [H-RP-PvX] under reconstruction!
