I know when I got the new armor and I glamed over what I had on. I got lucky with the pants I had on. Which where the Orbonne Monastery pants and I've just worn them with that glam. I was trying to be ready, also when I did the dungeon the first time. It felt very odd going through it as a DPS, when I've gone through the story as a tank. 😅
Lucky! I was less so. Lol. And yeah, running content on a non-tank is very unnerving, especially if that's what you've done for the majority of the game.
