I finally have beat Inferno with all five character classes without using the auction house! I essentially played each class at the same time. I'd complete an act with one character and then move on the the next character. My barb was the first to beat Diablo (1.04) the day before 1.05 was released. My witch doctor and Wizard then beat him the day 1.05 was released (MP1) A couple days later my DH beat him. (Toughest fight by far, almost always was killed in the shadow realm by my clone). Took some time off and farmed with my WD and then tried tonight with my monk on MP1. It was by far the easiest of the five battles, but I also had 29% crit and 750 LoH for the battle. My rules: No AH buying (selling ok) No trading Gear can be traded between characters, but only if they get an upgrade (ie - no gear swapping BiS) Questing was always done solo. MP (seldom) were only for farming purposes.
