Anyways, been doing the new Queen's Jubilee patch since it dropped last night. There's certain stuff they're trying to do that I think could be done better, but I don't want to get into a deep mechanics thing since most of y'all couldn't participate.
I will say how cool the area is and try to describe how it works.
They rebuilt an area of the main human city (Divinity's Reach) for the Queen's 10th anniversary. (lore stuff)

Inside this area is the Gauntlet or whatever. There's two things, but they're not entirely separate. At the mid level is where the vendors and the npcs are. It's the safe area and the respawn area if you die. Below this area, six different zones are laid out in sections, each featuring a different type of land/architecture and type of enemy faction. Each enemy factions has regular mobs, vets, champs and a boss that spawns. This is the open PVE area where large groups of people fight.


Above this area are these glass arenas hanging from the ceiling.

These are the Boss Challenge arenas. Only one player can enter and fight the boss of their choosing. (You can add "gambits" which give your character extra difficulties to overcome for increased reward.) You select a boss, you select a difficulty tier, and you can add gambits for increased reward. When you get in, it's instanced but not. Nobody else can enter, but everyone watching from the walkway can see you fighting. So can the players below in the open PVE area since it's all the same zone. An announcer says when a new challenger starts and it says when a challenger is running out of time to kill the boss. Here's the funny bit: If your boss timer runs out, you don't respawn up top. Instead the glass floor breaks away and you fall to the area below. So you can watch others do boss challenges, but you can also have them randomly fall to their death as you're fighting in the area below.
