Ok imagine that when leveling in the game, it would take a year's worth of work to make it to level 100. That's a rate of 1/1/1. Now make that 2000/2000/1000. Yes. In one day, you can hit level 255. One year's worth of work becomes one day's, or less since you get to double the normal level cap. That's pretty much how huge a jump this is. But you'll love it, because it let's you get a feel for the game without the restrictions.
