Do you also break every pot and touch every body cause they can still drop orange? Also a dude played for 24 hours straight on twitch yesterday doing exactly what you are describing. You know how many purples he got? 1. 1 from killing every mob in the strikes and moving on to the boss. Know how many blues he got off the bosses? 200, know how many he got off of normal mobs? 100. I'd rather speed through it and get double the blues thank you very much. Diablos strategy doesn't work in this game, or else high level mobs would drop high level items and low level mobs would drop trash.
