IMO we can do without the "Kill 20 rats" quests as a form of progression. I like the current setup where you have repeatable leves to give people a short boost of exp, we can grind if we want, and we have various one-time quests around the world that are a little more story driven and vary between going to places for clicky ???s, killing things for drops, and things inbetween. One of my favorite parts of FFXI was how story driven even the most meaningless questline was, and how some of them had you going all over the world to all sorts of places (even if more often than not the rewards for the quests were absolute garbage). Hopefully in 2.0 when they start focusing more on content than redesigning the core game we will see more of these quests (but with more relevant rewards for your time).

I wouldnt expect them now considering all those scripts and triggers are a lot of work to create and will all ultimately get thrown right into the trash can the second the new world goes live, it's just a waste of development time
