MapleStory 2, welcome.

The miracle system would be fine if they had an in game method to acquire them that wasn't event oriented. What you're asking for is way to high. By supporting changes that give the players a slight advantage over the odd's, by seeing bigger profit margins, the idea would be they would experiment with other things.

Really the big change they need to make is allow you to get NX through bossing/pqing. You complete it you get 1 to 2 dollars depending on several factors.

I strongly disagree. The miracle system (I assume you're refering to potential) does nothing for the game other than make the issue of power creep several times more serious. Little example: at lvl 150, a mere item with 12/9/9 % legendary pot lines will give you 225 of your main stat. thats AP equivalent to 45 lvls and 6 to 14 times the base stats of a lvl 140 item. Even if they had put a method to get cubes in game its simply ridiculous, we didn't need that kind of power, specially considernig they keep on revamping classes and making training more and more simple. What we needed was more strategy based content, stuff like CWKPQ, complicated but not impossible to do, but I guess just raising stats and getting tons of money at the same time is way too tempting to ignore.

If potentials had been based off item stats instead of player stats it would have been much better as not only it would have increased the importance of good drops and scrolling but regular folks could have also taken advantage of it by crafting and scrolling items, selling them and making money to then cube/buy cubed items. As it is right now its only a trade between those with money and Nexon.

Edit: and I forgot about the second branch of potential, whatever is called...
