Something I have considered for the last several years on Imperian is removing experience loss from the game completely.
Dying would never result in losing XP. The penalty from dying is the time lost from dying (which sucks).
This change would require removing experience gain from killing a player from adding XP to the overall XP/levels. (We can keep the pk level xp moving up and down) I would actually like to keep XP gain from PVP on, but people would farm it no matter what rules we have in place.
One of the main reason people hate dying to other players is the loss of XP. I am sure many of you hate dying because you are losing to another player, but at least the XP sting would come out of it.
The reason I have never made this change, is because it is such a foreign concept on our games. I keep telling myself that it has always been this way. That is the worst reason in the world to not change something though. Losing hours of bashing work sucks when the only way you can get it back is from hours of more bashing work.
Another thing that popped into my head would be allowing players who die in their cities (from raiding usually), the option to instantly res at a central city landmark. They would res with temporary grace so they can def up or opt out of whatever is killing players in the city. Something like - You have died during a raid, type RESURRECT to be placed at Kinsarmar Crossroads. This includes things like mob raids from events that can be annoying as well at times.
This would take some of the sting out of dying when getting raided, and may help slow down raids that never end.
Anyways, a couple of ideas there for you to give me some feedback on.
