I'm not exactly a new player, but I had this question and I thought the answer would be good for new players to hear as well.

Ok, let's say you're playing a rager wanna-be (or whatever cabal). You got your skills up pretty good, and you're looking for someone to pk. You check who pk and find that there's only one mage (if you're a rager) logged on in your pk range. However, you've fought this dude twice before over the last two days, and both times, he died without hardly scratching you. But, it's been a while since the last time you killed him, so you go wax him again. You take a look at his race, notice he's a drow and suddenly realize, you don't have a mithril weapon for dealing with drow (even though you don't need it with this guy, there will be other drow eventually). So you go get yourself a nice jeweled dagger, come back, and as you walk into galadon, there's the same guy you've waxed three times, no longer a ghost now, and sleeping at Market Sqare. No tribs around, no witnesses, you don't give a jack about tribunal laws, what do you do? Do you wax the guy again, even though you've nailed him three times already and the last time wasn't long ago (and you know that with the jeweled dagger you'll probably one-round him), or do you take pity on him and leave him be, turning down the chance to kill a mage when you're applying for the village? I always feel sorry for the guy in situations like this, but if my character has a crusade to kill (such as a rager), would it not be bad RP to pass up the chance? Or would it be worse RP to spam kill someone who doesn't stand the tiniest chance of survival? Decisions, decisions!
