Ok, first "dungeon" in this game aren't hard. At all. They are DF, instanced stuff, basically the bottom of the barrel. There is not even "competition" like with hunts were it may happen that you don't get the reward.

It's not compelling to do dungeons for a few hours, when I can spend the same time with hunts and get more out it than I could the dungeons. Plus you get Allied Seals. Three birds with one stone. Hunts should have been an equal alternative to dungeons, not blow them out of the water.
If you like dungeons, do dungeons. If you don't like dungeons, don't. I mean, you are the one who said myth shouldn't drop from hunts, right? So myth dropping from hunts shouldn't be a big deal for you. You clearly don't want them. You would prefer to go back to SR brayflox over and over.
