I just switched from dual wielding on my DH to 2H crossbow. It's a bit of an adjustment. What skills should I be using? I'm currently using Piercing Arrow and Multi-Shot as primary/secondary, and my other skills are Caltrops, Vault, Impale, Spike Trap, and usually Marked For Death.
I'm dying quite often in Act 2 of Hell despite being (in my mind) fairly decently equipped @ level 56. All of my equipment is Dex/Vit, and now most of my equipment also has Resist All in addition to one other type of magic resist. My rings are admittedly lacking. Even still, I do pretty well solo, but I feel that survivability/effectiveness in a full game is a truer metric of performance.
Oh, my stats: Definitely >25K Life, DPS is either 14K or 17K. I'm not at home at the moment, so I don't know for sure.
