waiting is a part of it. Just removes the need to run to the corpse and the need for the priest player to be too active.
We used the gy at the back of the bareback brawl for privacy while I just watched Dr house on my other screen as my friend killed my holy priest over and over.
"Edit" we did discover that if you kill someone too fast it wont reward a mark but that was maybe one out of ever 7 kills or something insignificant
