You don’t get mad when a hunter kills a mob, when a miner starts mining, when a crafter starts crafting, or when a pilot flies to CND or CP.
A fundamental difference between killing a mob (red dot) and killing a player (green dot) is that when you kill a player, you directly do something that influences another player (typically, sends him to revival).
Technically, red dots are controlled by a computer, and green dots are controlled by humans of which most have feelings. Or as seen ingame; green dots revive and remember having been killed and red dots just die and new ones without previous memory of hunters are being born.
Depending on situation, the other player may think it's ok or even good (dodge skilling in ring, for instance), or it may be a big menace (a low-end miner without TP-chip who just got a claim in middle of nowhere, or a hunter halfway throgh a mob got killed by a long-distance shot in the back). The person you kill may be in good mood (just ignoring being killed), or bad mood (getting mad and wants to either come back for revenge, or puttig you on a "KOS" list). Generally, it's probably not as fun getting shot in the back as it is to fire the shot.
Also equipment and skills differ. A typical pk:er have practice, a low-lag computer+connection, ingame skills/HP and equipment. Keep in mind, though a full set of Infiltrator is cheaper than a set of Shadow, it's still not affordable by everyone. Even if LR66 is good, unless you have good pk skills, you have little chance against someone who fires at you with tango or mod dar.
Back to the original question: Should pvp be on or of in, ie, dome 16?
First, think there are a number of legitemate uses, beside pure pk:ing:
- A miner wants to get rid of another miner who's bombing at his claims (not relevant since there are no veins anymore)
- A hunter sees a miner running for him with a tail of aggroed mobs
As I see it, the above is the top reasons why pvp is on. Now if people uses it for pk sprees and causes problems (for instance shooting hunters, including hunters running through the dome since the nothern TP doesn't work), maybe the mis-use of the pvp feature is bigger than the actual use of it.
As for pk:ers missing a place for pure pk:ing, maybe it could be examined if there is a better dome suited for it, without rare mobs & mined stuff, or if MA could implement some sort of ring.
