Oh wait. Its exactly the same.
Also, there are plenty of FF games where you grind stupid amounts of random mobs OVER AND OVER AND OVER AND OVER.
The difference is that consumers expect fast pacing for leveling and gearing so they can focus on running raids OVER AND OVER AND OVER AND OVER.
If you would rather run raids over and over and over rather than dungeons over and over and over. That's just about every OTHER mmo on the market.
