My experience with
http://grievancegaming.org/
I came from a number of games where I always ran with a trusted group of friends. We started in EQ, moved to DAoC, then WoW.......But as time went by we lost folks along the way. We couldn't raid anymore, but we had the fun of being with each other. Then one day, no one really played the same games anymore.
I answered the "Tired of Guild Shopping" post by Grievance for Elder Scrolls Online. They came from some of the same backgrounds of games I knew. Somehow, this group combined the best of both worlds: close camaraderie and end-game raiding. People were respectful, they even mandated a "No Drama" policy. I joined and haven't looked back.
I love the people here. I joined them in a Real-Life get together in which 70 of us dined at a restaurant, (panicking the host of course). Grievance plays multiple games, and you can join them in any. Youtube and Twitch broadcasts, some for charities!
I found the last guild I ever need to join. Maybe you will too!
