There's a bizarre legacy to the final few encounters of Final Fantasy XIV's original main story, which has left the trial Camp Westwind, and the dungeons Castrum Meridianum and Praetorium an uneasy fit with the MMORPG's modern content. As previously announced, the devs are revamping those encounters for patch 6.1, and in the most recent Live Letter, they've explained exactly what form that content will take.
Cape Westwind will no longer be an eight-player trial - instead, it's going to be a solo quest battle. If you want to see it again, you're going to need to check it out in New Game Plus. Castrum Meridianum is dropping from an eight-player dungeon to a more traditional four-player dungeon.
Praetorium gets an even bigger change, though, as it's now three separate encounters. The start of the dungeon through the Gaius battle will now be a four-player dungeon. The Ultima Weapon battle will now be a four-player trial called The Porta Decumana. And the Lahabrea fight will now be a solo quest battle.
