You know what will make me rage?

Randomness in Nexon's decisions is a huge factor in whether you gain tons of money or lose tons of money, but there is a certain degree of predictability to most things. You don't have to regard what I'm saying here, but in this case, you may want to do some research as to how the erasers might be used in ways other than the seal chair quest, flaming katana quest, and chair exchange in other versions. Also, consider which versions have real and fake erasers, which versions have the fake -> real eraser exchange through Arwen, and the chances of getting data imported from those versions. I know maplesea had the fake to real exchange, but I don't see that getting copypasted soon because we just got Malaysia. I'm personally not sure which other versions may have that feature.
