Though I have just played for approximately two weeks (was bored af waiting for a character to be deleted on my main universe), I feel like other worlds could benefit from the match if cubes were purchasable with Cheap Maplestory Mesos. But not just some cubes.
In case you have achieved Master and Meister ranking levels, I think you should be able to purchase Master and Meister cubes (or at least the crafting materials to create one) straight from Crafting Merchant Nack. The standard cost per block could be about 6m to 10m per block with just 3 of each purchasable daily. The price is cheap, so the poorer players who attained master and meister levels can purchase at least 1 per day, and the cap is so extremely rich do not just purchase hundreds of cubes at once and start selling freshly cubed gear.
The option for crafters to build cubes must be replaced with something more based on craftsmanship, as I believed that Cubes should have been an alchemy thing previously. Imagine if they can construct Battleroids (low pass rate), Outlaw Hearts (low pass rate), Superior Lidium(average pass rate), and Titanium hearts rather(Below average pass rate)? Or rather something brand new and unique like armored attack mounts such as tank (low movement speed, low fire speed, high damage rate, high defense speed, can flash jump) and airship mounts (high movement speed, average fire rate, low damage rate, average protection rate, can fly like xenon) that could attack in normal maps and bosses?
Particular attack mounts could be a cool thing by which Maplestory items players can attack with vehicles that also protect them from perishing one time per use. The mount is removed upon being ruined and cannot be "treated" with potions.
I believe players who usually craft cubes would still buy them to craft extra cubes, since you can only buy so many cubes every day, individuals who are forced to buy more to find the "perfect possible" would be willing to buy the extra stuff (cubic blades( and fragments) to create their very own. Being able to buy cubes from nack would be like a daily "free trial" and if you wanted more or didn't wish to buy them all the time, you'd have to create them to get "free*" like everybody else.
