Monster Name:
Any S-rank mark (namely Naul in Coerthas and the giant rock monster in S Than; Im sure I'll encounter this again though)

I realize the locales are being flooded by players trying to get their hunting logs done but when I have others' spell effects off and have moved away from the group I should be able to at least target and hit the monster rather than just see it from afar or when it dies. Needless to say, I am completely unable to do the hunts at this time.
