One of the MMORPG future that in RPGs isn't available is Player Killing. Do you like it? Do you do it? Do you consider it appropriate? How do you react when it happens to you?
For me, I like PKing in some games, where PKing is part of the real game, but in many games, PKing is not to good, like in lineage for example, where you fight with a RaidBoss, and get PKed when you almost finished the Raid, and the PKer takes away your drops. That's totally frustrating!
What about you guys?
