Finally got a chance to do some recording during a Red Dragon raid. Unfortunately, I had to leave halfway through it, so I didn't get as much footage as I wanted.

The guilds I saw involved in this raid were Outplayed, The Obsidian Order, and Trino Police (there may have been more, but I didn't notice).
