Because in videos I just see how ppl can carry and drop resource items - actually not things like cloth scraps etc. - u kinda need to discard them to get new inventory space.
I dont think this is planned. I think items you "drop" were meant to be placed into a "junk" status on the server where discarding many would make junk piles over time. This has not be put into the game yet.
Right now dropping items will delete them from the game. There are a few times (baskets, grass, scrap metal, scrap leather, logs etc) that can be stacked on the ground. Items like tools, armor, weapons etc. Can not be placed on the ground they must be placed in baskets, or pouches.
I would like to be able to do this. Imagine if you ran a little trading hut and you could put your wares on display =) Maybe being able to set permissions on items stacked on the ground would keep people from stealing the display items, but you should only be able to set permissions if they are within tribal borders. Anything else would be fair game.
