Hey y'all! I joined a month back and I've played through till 170 without a guild. Sucks, but I just remembered this forum was a thing so if there are any guilds in the NA timezone (mine's GMT-8), I'd like to toss my hat into the ring! ))
R>family! We are mostly NA guild! But before you commit take a look at the recruitment tab on the forums and look through the guilds to find the one that you think fits you best.
Basically all the guilds that I know are great options
