I had a debate last night with a fellow guildie. Perhaps somebody can settle this definitively:
He was saying that when you're attacking an NPC and some stranger / player comes up and "gets in on your action" uninvited, that the loot drops are completely instanced for both people, so that person's "uninvited help" has zero effect on what loot drops for you.
I told him it sure seemed to me like every time somebody butted in on my action like that, I got a lot less loot out of the deal (typically, one lousy gold piece). So, I get very annoyed when somebody jumps in like that.
What's the word? Is NPC loot "completely instanced"? Do multiple players hitting a single PC each get the same loot as if each of them had hit that NPC on their own several minutes...or even days... apart?
Thanks!
