That would be able to tank a few minor hits but smal mobs. Anything big will still hit you at 40K dmg in act 3 and 4
Then how am I not dying to things even with 200 resist 2600 armor and 30k hp?....
EDIT: I just logged in to check.
I got 47% DR from armor, 44% from phys resist. And the mobs at start of act4 hit me for 26-28k. I went in and tried 5 times. (Screenshot: http://i.imgur.com/XNmqq.jpg).
That means if I had 0 armor it would hit me for 28k / 0,53 = 52.8k dmg.
If I also had 0 resist it would have hit me for 52.8k / 0,56 = 94k dmg.
So without resist the first act4 mobs hit for 94k dmg. With the tank build I suggested that would be 94k * 0,2 * 0,2 = 3,7k dmg.
Please correct me if my math is wrong.
If my math is correct the tank build I mentioned could tank ac4 fairly easy. Even the opressor charge that does 220k with 0 armor/resist would only do around 8k dmg to you. Which is nothing with 75k hp.
Because your arent in Inferno act2+ bro
