Leves are not story driven. They have absolutely nothing to do with the story of FFXIV and are just daily quests. "Hey, these guys are pissing in the aquifers, go kill them."
Quests and side-quests are story driven and I find them fun because despite the fact that they are mostly run from point A to B to C and talk to people, they reveal more backstory and story on the game. Leves do not.
