That's what happens when you leave your business closed for 24 hours. They shouldn't punish players who were unable to log in before some arbitrary time for it. Especially when the game is down so frequently.

Heh, whether or not they deserve to lose revenue is another matter entirely.

Also they don't lose revenue. People still buy NX when the game is down

But the aggregate amount of nx charged in the short term is reduced. Having maplepoints lowers demand for nx in the market, and makes less nx be charged. The compensation is to not lose customers, for long term nx sales its probably the right move, but the sweet spot for Nexon is compensating people just barely enough to keep them playing (and by playing I mean purchasing).
