I do not fully understand why item drops, even gems and runes, are of no value to vendors.
-Increase sell values, decrease drop chance from regular monsters, decrease xp gain.
-I'm used to grind crafting materials and sell crafts for gold.
-I don't mind regular mobs spawning every 2 minutes after they get killed.
-The crafting system is okay, but maybe formulate new craftables that makes use of gems and other valuables (which usually end up as trashes). Vendors will surely not mind paying more than 1 gold.
-Get rid of chipped, flawless and perfect prefixes to gems. Decrease the drop chance of gems, and maybe instead of using gold for Gamble we can exchange those gems for the items.
-I am not aware if what I just said are all possible, and I think my suggestions will not be destructive to MXL so I decide leave a post here.
