When you take away the incentive to grind on a game that is centered around the aspect of grinding it can be clear of one thing; the decision makers at Nexon DO NOT understand basic economics or the demographics of their player base.
The economy of Maplestory will come to a grinding halt. Players will lose motivation, alongside any competitive edge that might have existed, because they are being punished for actually wanting to play the game. You have overreached your hand by being greedy in your efforts to increase the daily login data rates to show to your shareholders. You've severely undermined one logical foundation of any gaming corporation, that when you take care of your player base and put them first the player base in return takes care of you.
Remove the Sol Erda daily cap and you'll see a more fruitful longevity of this game. Don't and watch GMS quite literally topple in on itself within a black hole of distaste, disgruntlement, and dissatisfaction.
