First, it's called counter-
kill. as in it's an attack (you even get exp when it activates and hits a monster).
I do agree however, that people are abusing the no pkp rule (like me

). Since it counts as an attack, you should get the pkp's like an attack.
Oh btw: some people will won't read your first post and vote "no" right off the bat simply because you're saying ck as a whole is unfair, not the pkp part of it. you should have mentioned that, now there's going to be a lot of "no" for misinformation
