Greetings,
Thank you for tagging us @TeleTesselator. First, we need to clarify that in PvE players shouldn’t be able to kill other players’ thralls/pets/mounts. Any means to accomplish that are considered exploits.
The same goes for PvE-C outside of the conditions this rulest allows to.
As for the guidelines, we have been working on ways to make them more visual and better explained.
