In game Suggestion.

Being able to blacklist a drop.

I just want to farm for hours and only get the drop I need so I dont need to waste time processing stuff.

 

simple solution:
you just need 1 slot for the current stack of your target item. until the stack reaches it's maximum capacity, you can still get that drop item even when your bag is full.
once the maximum capacity is reached, you just need to discard 1+ items to clear up a slot for the next stack.

 

Thanks for the tip good sir!
