Leves are the FFXIV equivalent to cleaning your house. Repetitive, monotonous and they keep coming back.
Think of Leves as your average, low-quality MMO "quests," but replace NPCs with the same, silent crystal. Skip the generic text either way.
Pretty much, with (at least for me), one minor flaw that ended up being a pretty big deal, and thats the location. Sure in wow/rift, I know I'm gonna go out today, leave a town and kill 12 wolves, but at least tomorrow I will leave a different town, and go kill 12 wolves in a different place. Maybe its not a big deal to some people, but it was killer for me to go out and do the exact same thing day after day. Not just essentially the same, but exactly the same thing, for rather long level ranges. its a minor fix, but since the mobs are pretty much instanced/phased (lets not bring up that ridiculous argument again), I don't see why they cant spawn the locations in a variety of places, or even randomly.
