I remember alot of posts awhile back about this, and thought it had been fixed. But last night I tried charming 2 different mobs in the demi plane of life. Both wouldn't ever attack. Is this a bug returning? Or was it never fixed?
I don't think it was ever fixed, it's just that charming in that zone actually does work... in some areas. Generally you can use a charm pet if you are in the center of the zone; eg on the circular street that surrounds the pit. If you move far away from this area, they tend to stop attacking.
