This is a horrible idea for people who play with friends and are considerate.
If I'm doing something like shiva and the pld sword drops and I roll need for my retainer, then someone asks for it, I'd then be able to leave and give it to them.

With this idea it throws that out the window so impatient people can get their drop quicker.
The current system is nice, however sometimes people will not lot hoping you will leave, its fine though since its yours if you stay.
