I like the dungeons, but it is not really challenging. I do them just for the levelling and at max lvl almost never again. It is such a shame.

It would be nice to make dungeons more challenging, some sort of mythic+ dungeons system that WOW has. With all the dungeons that FFXIV has, this would be fantastic! More challenge with affixes that change overtime and higher difficulty's like a tier system +1,+2,+3 and so on = more replayability.
Maybe even a ranking system.
I am just spitballing some ideas here, but we really need some improvements with the current design of the dungeons.
At least make the hard work of designing dungeons and encounters pay of, to stay relevant long term!.

/Thanks!
