I wouldn't mind having a larger party than 4, I've always felt like 5-6 is better for a party size personally. That being said, I feel as though Palace was their solution to DPS queues since it takes whoever in whatever order they queued in. Now, I do want to add I understand that part of the issue with palace is that there are plenty of fights where if you don't have a healer it's basically impossible. But I attribute that more to a failure in design, specifically, if you're going to create content that can be done without a healer then it needs to be tuned assuming there are no healers or HP recovery, that is currently not the situation.
