Hi Arkiri,
Our guild, Braveheart, (based in Argent Dawn) is newly-formed and recruiting active players for Shadowlands (including raiding, M+, roleplay and social events). We also believe in making friends while playing the game, having a laugh while doing so and clearing some content along the way.
Most our members so far are from the UK too (including myself!) so we would be working within the same timezone as you. Check out our recruitment thread here for more information or add me on my battle.net (Hystericxl#2223) and we can have a chat!
