When you have an item in your cursor make the left click in the world move the character, as if it was alt+click. Make items droppable only with ctrl+click.
I see no valid reason to have functionality of dropping items with left click.
I keep losing equipment all the time because of that, and it infuriates me.
2 most common scenarios:
- I'm switching equipment but there was slight lag, so the item wasn't put in proper place staying at the cursor and I already left clicked to move
- I'm moving with equipment window open and I missclicked piece of the equipment so it lands in my cursor and I continue moving losing the item on the next click
