After the next reboot there will be some changes you will all see regarding Masters, and mob leading.
Global mob leading has returned, but there are a few restrictions placed upon it.
If you are leading a mob and it dies outside the zone you got it in you will lose 2 QP.
If you rent or quit without returning the mob to the zone you got it from you will lose 2QP.
This policy may be tweaked as needed, however those are the rules as they stand now.
