disenchanting would make more sense if it gave things like magic dust to enchant the items for better stats rather then soul crystals that have yet to even have be implemented in the game, this would be really helpful to all so be sure to thumbs up and help it be seen by the game moderators :-)
the effectiveness of farming is primary based on the limit of the bag space i agree having a coin drop would be nice but as mentioned it would affect the games economy also reduce need to open up bag space to accommodate for more salable items from any farming run.
I get why Monsters don't drop coins, with the AFK option mode the coin system would be flooded and would mess with the current in game merchants both real and NPC
