This is just a quick post on the ridiculous effects of All Resistance in Diablo 3. As a Barbarian, this is apparently the most important stat. It was never more apparent than an Inferno Warden and Butcher run I did last night.
I was in a group with another Barbarian. I died constantly. He died rarely. I can't remember him dying once as a matter of fact. The guy was taking hits like nobody's business. I inspected his gear and found that he was rocking A LOT of All Resistance on his gear.
I am currently working on building up that stat. Unfortunately, it is quite expensive. I think I have two or three pieces of gear with the stat on it, and I will be looking to grab some more.
I think that it is also the most important stat for Monks. Melee classes get blown up big time in Inferno. And for the ranged classes, make sure that you practice your kiting and defensive cooldowns, or you could well be one shotted.
