How do you think maplestory 2 will be?

Much better overall skill and quest design. Skill design that could result in different, viable skill and stat builds for the same class (no, I don't consider having to choose between Inferno and Thrust as a Ranger to be an example of different viable builds for the same class). More quests that are actually worth doing. These are from the top of my head, and I'm sure that there are other issues that should be addressed.
