Multiple difficulty scaling dungeons

[Yeol]

Right now in FFXIV the dungeons are very easy. Basically in most of the dungeons I see tanks mass pulling the entire mobs until they face a wall and then dps AOE them down.

The reason dungeons are easy is because:
(1) Most of them are story dungeons. People will be doing them with low lvl gear. It has to be easy enough for 1st timers.
(2) Daily Roulettes. Now imagine doing a very long and somewhat hard dungeon every day. Not many will like this, especially those that farm them for glamour.

If you are going to create an optional harder dungeon, it has to give good rewards or else it will end up dead like The Diadem.
At the moment, giving gear as a reward is out of the question.

We already get iL330 from creation that can be upgraded to iL340 with tokens from Savage raids and 24-man raid.
Crafted gear which is iL320 is more than enough to clear any current content (Savage was cleared with crafted gear).
Are you going to give them iL335? Not good enough. People that can do these hard dungeons are better off doing Savage for iL340.

We have PoTD. You can do it solo or with a group. SB will introduce the next floors for it in later patches.
PotD gives all sort of rewards. Titles, mounts, minions, tomestones, even EXP. And a challenge on top of that if you go for higher floors. So it will never be dead content.
