Have a 58 monk working through Hell and my gear is starting to suck and Im hitting a roadblock and just started working through ACT III. Im just not getting anything from drops while questing and I do all the side dungeons in each area. But I struggle badly on most Yellows, and the triple blues...forget about it. Is there a certain set of steps in a particular Act that are better for farming than others so I can improve my gear? Theres just not many people posting 55+ stuff on the AH yet, or even level 50 items so the stuff thats there is really expensive.
Also is this a game where I need a class just for farming or can every single class solo farm just as good as long as they are geared? I also have access to a level 57 Barbarian with decent tank gear I could switch to if that would be better. Or would it be faster to just roll a Witchdoctor?
