Our locks drop their portals just a few yards behind the group giving them a quick way out, but plenty of room to run the orbs. Thus far, portals have not been an issue.
And of course, I can confirm threat drop mechanics to cause the issue. Our resto druid was getting beaten on by whelps and someone BoPed him, sending the orb spinning around the room. Our priest has also faded whelps at the wrong time and done the same thing.
