Dailies should disappear completely.
Or provide an alternative progression path that is not tied to time, but to skill. But that is difficult because FFXIV, like many other MMOs today, have forced itself into the classic questing framework where the quest system is only capable of producing bland content.
In terms of development costs, it's cheap and easy to produce these quests. You have templates for quests with actions and triggers all pre-written. Just change the targets, change the co-ordinates, fill in the dialogues with some filler, and there you go.
The concept of dailies was born out of reusing content, not producing content. Hence no matter how you tweak it, it's going to be boring and bland.
SE need to review their design philosophies on this. Are they going to keep trying to produce content while having their hands tied under a rigid content-reuse framework?
