I am not much of a Diablo player.

all I know is there will be a lot of loots.

question here is can I obtain the best gear without having to play the hardest difficulty. inferno i believe.

maybe hardest difficulties have higher chance of droping better loot. But you can still farm normal=> hard to get the same loot. Is that how it works ? or best gear only comes from the hardest dungeons.

and if we don't use camera zone/pan, broadcasting mouse clicks can work somewhat. After all, you click at the same spot relative to your screen resolution anyway. So your character will be in sync for movements.

Then I just use 5 sorcers to AOE farm all day for AH profit.
