@ Zeraph: Yes, this is what I mean.
Your suggestions might be an option to limit indirect PK, but the harvesters might just overrun the area to keep killing every MOB until no player bothers to come there anymore, which will have the same effect, only take longer.
Also, they could group and have several small trains instead of one large one.
Furthermore, if this was implemented, ppl. could just get a train of three harmless monsters and simply walk the dungeons of doom without fear of ever being attacked by anythign of serious size...

However, if the MOBs in the train would start killing each other, that might be realistic, but only dependant on the \"cooperation level\" of the MOBs, and also can be abused by players to let the MOBs kill themselves, so that they then can take the loot without any danger. If, however, there would be no loot if a MOB was killed by another MOB, that would not be usable for anyone but griefers.
And yes, PS is trying to be RP oriented, but the problem is that you still need fights and public spawn points, mainly to provide for questless danger and recources for the economy.

@ AgentZ: As Bobkat and RonHiler have already answered your objections to my reasons, there isn\'t much for me to add. However, I\'d like to see how some universal ethics would make everyone be a slave? It is my opinion that there is no objective, universal ethics, but there is a subjective universal one, which
will be the same for everyone, regardless if they act on it or not. This, however, is OT so I\'ll just shut up about it.
@ Acraig: it\'s good to read that the issue is being thought of and going to be adressed.
@ Adeli: You wouldn\'t be flagged as a cheater, because, contrary to the harvesters, you\'d spend considerably more time doing other things. As with everything, the system, however it will be implemented, needs to be fine-tuned and also will generate false positives as well as false negatives. However, just as with the conventional anti-cheat systems, the false positives can be addressed if the system is tuned well so that there will be very few of them.
