For the guy interested in my mates Barb stats from the other day, at the time (act 2/3):
47k health, 850 resist all, 10k armour (ish, wasn't 100% sure but it doesn't go up a lot anyway, its only 11.2k now in much better gear), 1900 health on hit, 19k DPS.
And speaking of act 2.. Brick wall!

really wanting to get through it solo but its just not happening with my WD =/
Tried three sets of gear with no success.
38% attack speed, 39.2k DPS, 30k health - no luck.
750 resist all, 61k health, 21k DPS - no luck.
550 resist all, 33k health, 20k DPS, 1600 health on hut - no luck.
Ugh ;(
