I do feel like scrapping dungeons for adding ultimate among other content does set this bad precedent that they are willing to stop developing content that appeals to most players in favor of developing content that only a very few will even attempt. If they do develop something with a wide appeal then excellent. This game does not lack for diversity though, its just that players usually want a diversity of content within what they already do, so things like golden saucer or gathering or crafting don't fall in their realm of content. Dungeons will always be the first thing cut though for the pursuit of other content, because some very vocal players constantly talk about how much they despise them.
