Oh, that melee/ranged divide! Monk struggling Hell.

Bring back blinding flash! I would replace one of the attack moves with it. This skill is amazing, especially when runed with faith in the light which gives a 30% attack bonus for 3 seconds. The double flash rune is also useful before you get Faith in the Light. Combine with serenity and you have much more leeway against attacks.

When you get to inferno, you'll need to get some resists. Vit with no damage reduction is worthless. I had 50k hp in hell mode and died much. Now I have 40k with a lot more resists and armor and don't feel much in act 1 inferno. It's simplest to replace transcendence or resolve with one with everything, and just get one kind of resists as much as you can.
