I believe that PK\'ing should be allowed, but to certain standards...
1 - Massive PK\'ing - Yes!
2 - Selling of the items looted from someone\'s corpse - NO!
3 - Bounties on the head of a PK\'er - YES! YES! YES!
4 - Tag that marks someone as Murderer so that everyone in the world knows you PK - NO!
5 - New Job: Bounty Hunter - YES!
Now you see here is the idea that I have... Allow PK\'ing to happen, but also for each person you kill you get a bounty put on your head. Say for every 10 people that you kill the bounty moves up by 25%... THUS... The first 10 people you kill will cost you 1000 currency pieces per kill... THUS 10000 Currency Pieces for 10 people, but on your 11th person it goes up by 25%, and thus moves up to 11250, because it went from 1000 currency pieces per kill to 1250 currency pieces per kill. Then 2000 at 21, and so on and so on... NOW, There would limitations to things like this, because people would Exploited that feature and get rich extremely quickly. You wouldn\'t be able to get another bounty placed on your head from the same person twice for atleast 10 hours after the first time you kill them... THEN You wouldn\'t be able to collect a bounty off the same account for nearly 240 hours (10 days). Now you ask...
\"If I am killed... How does this help me!?\"
Well, if you are killed, sorry... Die\'ing isn\'t supposed to help anyone, BUT your items that the person loots will be tagged and will not be able to be dropped except into bags that also will no be able to be dropped once a player looted item is placed into it. Or put into a trade menu either. EXCEPT for Crystals and for gold. They can\'t sell the items to NPC\'s either. They can use the item though to show that they have it. When used it dies just like normal wear and tear, and any charges used are used for good of course. S/He could pretty much use the item as if it were his/her\'s item. Once the bounty is collected though, your items are either teleported DIRECTLY to your bank (If there is one) or to your pack.. YOUR choice, because it would bring up a menu informing you that the items were back. All items would be brought back EXCEPT gold or Crystals...
This would allow PK\'s to show there place and even loot, but would give everyone a disadvantage along with an advantage.
