I know that full looting has been an area of contention for quite some time. I have an idea that may work.
What would happen if we made it so that when looting any corpse, you could only take one item at a time?
Let's take a look...
Player-A kills Player-B. Player-B is now making the trek back to his/her corpse. Player-A begins looting the corpse, taking what ever he/she can, but only at one item at a time. Player-B returns and begins getting their equipment back, again, at one item at a time. So, both are looting the same corpse, each with one item at a time.
Things that take place:
The killer has to be selective, for the killed may return to get their things back. So, the killer has to take what the killer can, before the other returns. It gives the killed a chance to return to their corpse and try to salvage whatever they can that remains.
It is possible to take as many rares as you can grab before the victim returns.
Veterans will know which is valuable, and which isn't, in such a way that they can strip the corpse of its most potential equipment, while still letting the victim to not be completely naked.
Possible disadvantages:
Those who type fast get more spoils.
Those who learn the lands and can run fast, can get back to their corpse and regain much of their equipment back.
They will know which pieces they want to keep and select those first.
Finally, it adds another aspect of the game, now two people are at the same corpse. It adds an element of danger and possible RP, since their might be more post RP because they are hovering over the same body, and it presents danger because the killer has to determine what is important, the rares, or being out in the open.
Oh, another side note, this idea prevents newbie and rank sitters from totally hawking a pkill and looting the corpses before the victim returns. Remember, even on mobs, only one item can be taken from a corpse at a time.
Just a thought,
Grey.
