You don't need to restate your name, we can see it. Saints: people who don't want to PK, in turn they don't want to be PK'd thats why having over 40AP allows you to heal (anything under 40AP can't heal.), besides if you are a "PKer" you should except the fact you're going to die sooner or later.
simpler: Saints don't kill, so they don't want to die, PKer's kill, therfore should die aswell.
its true that bombs, arrows, (and horses?) can hurt saints, but thats because a smart saint MOST OF THE TIME wouldn't be in a PK area, because they don't need to be, they're not a PKer.
