PVP gets removed again with tempest/luminous, right?

The point of Grand Battle is to recruit new Maplers and train them to fight against the Black Magician or in this case ''Mr. World Domination''. Anyway PvP in MapleStory sucks, so be glad it's going away.
And Tempest is coming in December for GMS. It was said on one of the Maple World WORLD videos I believe. So before Tempest, you're getting other content such as Fantastic Theme Park.

Ah.

Makes sense.
So much sense as anything else nexon does anyway.
