Does One Mob Count As A Camp?

[Gumbo]

I'm looking for an answer to something that happened when I was playing EQ last week. I'm not going to use any names or zones cause I want to keep this civil, if possible but I will explain the situation.

I was sitting at a camp that spawns more than one mob. One of the mobs is a placeholder for a named mob. I was at this camp for over an hour and I was only killing the placeholder to try and get the named mob to spawn. No one else was at the camp.

I soon had a group arrive and in the past, they would see what I was doing and ask me if I had the camp. I would tell them that I had the camp but was just killing the placeholder and was looking to kill the possible named. If they wanted the rest of the camp then they are more than happy to take it. 99.9% of the time, they would agree and we would all be happy.

This last time, the same thing happened except one player from the group started complaining that I was taking away XP from them because I was killing this placeholder and possible named mob. I explained what I was doing to this player and this one player kept complaining saying that I should be killing all the mobs instead of just one or two and because I'm not then they should get the camp, including the placeholder and possible named.

I want to know who is in the right here? Can I just kill the placeholder and possible named and leave the rest of the camp or do I have to kill everything in the camp to also kill the placeholder and possible named?
