JapanMS' Rebalanced Hard Core Mode

It doesn't have to be free. Nexon never had problems supporting the game pre-potential. I am perfectly fine with the older methods they used such as exp, gachapon and cosmetic items. I consider selling damage a big no no, especially if it is required for content.

Pre-potential, gachapon was essentially a more bulls'hit way to buy damage by getting lucky and selling rare acquisitions or even getting something you yourself can use. Without cubes there would have to be something to bolster an increase in power because otherwise the supreme server would have a years long peaking period where people are struggling to overcome the difficulty.

There are other things that you spend money on to get ahead though. Don't pretend like cubes is the worst evil.

People want hard and challenging content in Maple and allowing Cubes in supreme is the exact opposite of that.

Regular cubes only is already crippling. You already played regular maple without cubing right? You know how strong you can be with only 6/9% on each item. Do you really think higher level activities are possible in supreme through fusing alone? Without cubes, anything above maybe normal hilla would be a s'hit show. Without super cubes, anything above pink bean is the same.

I think mostly people just want it to not have potential because Supreme, while not pre-BB, contains many of the elements people loved about pre-BB Maplestory in its challenge and such.
This clearly isn't Nexon's intent, but its something many players who yearn for the more challenging (or Grindy) days of Maple want.

Cooldowns alone elevate training times by hilarious lengths.

I really don't think cubes take away the difficulty at all. You're still going to have to put in real work in this.
