Holocaust training Nihilum naggy raid

[Zallar]

Back on SZ when we raided we split the raid force, some groups were tasked with camping the zoneline and the rest of the guild killed the raid target. I'm not at raiding level yet but is it done differently here? Why isn't there zone control preventing the other guilds from zoning in? I remember on some zones we had the ogre linebackers blocking the halls to prevent opposing guilds from getting through.
