They also need to be aware of who is spawning which bosses, so they are not boss poaching on accident, or heaven forbid on purpose.
This is a big fear of mine too....to know what spawns a boss you have to be in the zone and know the spawns. I went in a few weeks ago running around the zone and saw Beast of Burden...I /ooc "did someone spawn this?" over and over. no one replied. after several minutes i killed it. I don't like to learn a zone that would run me the risk of getting the rep of being a ks'er...I prefer just to be the server asshole....but maybe this is more designed for the newer EZ players as i havent seen many of the old heads online much at all lately.
