When i farm act 1 i set the game up with the very last checkpoint before butcher

Hit Cemetary Gardens 1 elite in graveyard (sometimes) and then the 3 fast dungeons there with the chance of an event
TP to Festering woods 2-3 elites with chance of event and 2 dungeons with 2 elites
Head to northern highlands and kill everything (3 legendary pieces dropped during Khazra barricade so i include it everytime) proceed all the way to leorics manor all the way through 3rd level of halls.

You dont get any warden kills but you dont have to worry about story line so it works out better for me.
