A few mmos do have progression within dailies, though. An example could be something like, you're sent by the guild counter to investigate some garlean activity near x crystal in the black shroud. You arrive and pick up a couple of scouting quests off the aetherite (I think the current system of having to go back to the counter for EVERY LEVE is so stupid, it should be used as your base of operations, where the guy goes "You're x level, go visit y and see if you can help out!) to see whats happening, once you've done that a few times you unlock a couple of new ones to confront the garleans themselves.
This kind of thing could build up to where you unlock a boss fight of sorts, where youre sent out to try and deal with an officer or something. Once you've done it you can keep coming back, and perhaps varying leves would be given out on different days from then on.

^ I think something like that would be more interesting, and give a sense of accomplishment even for people with very little time to play. A cutscene or two and some lore revealed at the end of the chains wouldn't go amiss too.
