Now this might sound quite silly.. but I didn't think about using the chocobo to help with soloing fates (LMAO) but I still stand with my opinion.

Dungeon exp is useless and should be higher than fates, especially with the mvp system coming out.
Guildhests should reset per class, not character.
Fates should still scale in my honest opinion, even the bosses... make them hard but still possible.
