The problem I was having with this approach was that if the mob doesn't have LOS to me, am I going to be able to watch it? Otherwise, watching a single mob seems the logical approach.
My solution (for anyone searching the forums later) was to log in a second GM account. Target a mob with one GM, run to some obscure hiding spot. Then agro the mob (#damage 1). Follow the incoming mob with the second GM account.
So far things look great.
Thanks for the help.
