You are right, as a GM I know other GM's actively Headhunts the best players in my guild, and right now Tanks and Healers are more valuable than ever. So to have insider knowledge of these types of behavior these types of leadership within other guilds would be crucial to my own guilds survival. Honestly guilds have to be competitive, we can't all be number 1. We can't all hold hands and sing kumbayaa around the camp fire and call it good.
