Keeping your pet would be a huge help. on nights where my LS decides to farm multiple NMs my pet may live, but I have to immediately kill it to go to another zone, only to do it again (maybe 8 times a night). Even pup and drg get their pet back the second they step outside a city. Only jugs though, charmed pets aren't that much of a worry, and in fact below 35-70 on /bst-that is your leave command; it would be all too easy for that to turn into a situation where zoning does not lose aggro.
