Hi there, I am using the same spec as you except I use Ground stomp with wrenching smash rune instead of Leap and I use tough as nails, pound of flesh and ruthless for passives. I also use a 2 hander instead of sword and board.
I had a really hard time in Act 2 until I got my health up to around 40 k. That seemed to make a huge difference. I clear act 2 from start to finish several times a day without much of a problem unless I make mistakes and I never skip packs.
My stats are the following.
Armor 6,018 unbuffed
Resist to all With warcry 596-706
I don't have a lot of experience with using a sword and board in act 2 (because I refused to give into it) so I really don't know what your damage numbers should look like, but I can say increasing your hp could help out a lot. Your resist numbers are more than enough.
Earlier in my Act 2 play time I found that I went over board with resist (had just over 600 without warcry). It really didn't help much because the fights were lasting too long because I lacked enough damage to make a real dent before I had to resume kiting while waiting on ignore pain to come off cooldown. Taking out 1 mob was easy enough with Wotb but I found myself with enraged packs before I could kill them all. Just something to think about.
I'm sure you'll find what works good for you and soon realize Act 2 isn't as bad as it first seemed.
I'm now farming act 2 hoping to get lucky with drops and make enough gold to get my resists up so that act 3 isnt so painful. Got to Ghom with 5 stacks but he proved impossible for now so I'll stick to act 2 for a while longer Haha!
