I humbly ask that YP take a hard look at he numbers for how much each type of content that is being played and then consider why people are making those choices.
The rewards for FATE either need to be reduced, or the rewards for completing other types of content needs to be increased / expanded; as of right now 95% of content being played again and again is FATE.

While I'm glad there are things to do solo up to 50. There is actually very little worth doing in a group. Which is a crying shame for a game that you'd think would encourage co-op play.
Adding a small number of GC seals to dungeon mobs and / or completion, and increasing the exp slightly would make dungeons much more viable.

I also think that for some of the slightly harder dungeons, Sunken Temple and beyond. These need to be 8 man, and have mobs / rewards adjusted accordingly. I think it would be much more fun to have a larger group to play with as you are leveling up to 50 until leaving it until so late in the game
