Maplestory "High Five" Private Showcase

I absolutely hated the mastery book system and the way certain players and guilds, who "owned" the bosses that dropped certain books, controlled the market.
Then when the mastery books were changed so as to drop from normal mobs, botters profited.

And, as I said above, making the cores or core gemstones tradeable would mean that the meso-rich would have all the best cores, widening the damage gap further (as if removing the cap didn't make it bad enough already).
At least with each character having to get their own cores (can't even use your farming mules as Rebooters do for meso), the floor will rise evenly.

I agree with you that having everything in the game untradeable is a very annoying policy, and most of the time it's completely unjustified (or justified only by greed, see (P)SoKable items), but in this case I think it's for the best.

I agree with you on the way the mastery book system was done, but I feel like this system could be done differently since it appears the cores you earn are randomized. If cores are tradeable, then yeah, the rich get stronger, but where is the problem in that? The rich aren't somehow making things more difficult for the poor players. In fact, the poor players will be able to make money off of the rich selling cores to said rich players.

Rich players will always be able to get stronger more quickly, that's just an unavoidable fact, but restricting the entire system because of a widening gap (they don't even care about this anymore, as evidenced by the cap removal) is a bit silly in my eyes. Getting your cores maxed out will take an eternity on your own, and demand would always be there if they are made tradeable. The need for a spiced up economy may not exist in kms because of additional options, but in GMS... our economy is horrible. Nothing is worth anything other than pre scrolled and pre cubed equipment. Everything that drops from bosses and regular mobs is effectively worthless.
