I will give credit to Square Enix for making the Variant dungeon. This is how dungeons should be designed from the get-go, but at least they did it. It's challenging while solo, not so much in a group.

Problem is, no one's interested in it. There are rarely any parties for either Variant or Criterion dungeons. The playerbase just simply isn't interested anymore. Meanwhile, 20,000+ people are busy fiddling with their large honker mods at any given time. It's either that or raiding. The whole reason for this game's existence seems to have changed in the past couple of years. Sad, but everyone seems to love it. FFXIV has stopped being a game outside of raiding.
