Chardok

[Castigate]

Before Chardok AoE, almost no one ever went there, if Chardok AoE stopped, groups wouldn't magically start going there. Additionally, groups already occasionally show up there to camp the betrayer, and while there are difficulties, it is entirely possible for a group to do that while AoE is going on without either group causing problems for the other. Furthermore, everything that drops in there is so incredibly devalued now that no one is going to want to do it.
In short, getting rid of AoE would not accomplish what you are hoping for. It would just turn the place into a complete dead zone other than Royals and occasional pipe camps.
