EXP nerfs in the current KMST Patch.

Short term? They've been churning out new classes for four years now. How long do you think MapleStory's going to be around, anyway?

Maplestory survived off content the first 3 years of its creation. By focusing simply on classes, especially ones that can be made in 200 under 18 hours, it's a short time flare, a long term management problem.

Considering its a free game with a fairly large profit margin, I'm just going to assume awhile. Not that it matters to me, the game died for me back in 2010.
