Not for all dungeons, but I do wish there was a minimum ilvl requirement for the Heavensward leveling dungeons. Yesterday I went into the Aery (as MNK) and got paired with a BLM that had mostly i90 left side, right side ranging from i120 to i19 and a level 41/i43 weapon. Needless to say, we couldn't defeat Nidhogg because we couldn't get rid of the adds in time. From what I could see, he played his class pretty well, but just couldn't do more damage.

The min ilvl wouldn't have to be extreme, let's say starting at i95 for DV, up to maybe i120 for Gubal.
