I still see many sprouts (new players) on Ultros, even if they're just alts it says to me that people are still levelling all the way from level 1, I can't really imagine getting into lower level dungeons being a challenge especially as a tank or healer (dps queues however have always been a little longer than I'd like but that's to be expected), I still see low level fate areas alive and well also. There is plenty of reasons even for max levels to go back and do low level dungeons as well. As Millerna said, a good FC and LS can go a long way to helping as well! There's also still lots of reasons to run level 50 content as well! I personally love Au Ra, I feel they have a great personality to them and IMO they look fantastic!
