Yes, I've been doing just that as a workaround, but I've come around some problems like my WF starts whacking at the monster while it's still alive, hence getting hit by the mob in turn when it shifts from the pet to my WF. If I lessen the melee attacks though, my WF doesn't get near enough to loot.
I'm not sure if the bots I've seen are using this method, since they seem to perfectly execute 'walk-up-to-mob-after-it-dies-and-pickup-loot' each time. It doesn't matter if the monster has enhanced HP or anything. They also don't get hit at all by the mob, and they don't whack the monster with a melee attack either.
