Puncture in 1.2 vs 1.3

I currently don't have those Damage over Time nodes in the skill tree, so my puncture is pretty useless. I'm wondering if anybody has tried puncture in 1.3 with those new nodes? Is the damage comparable to what it was in 1.2, or is puncture now useless even with that DoT tree?

Check out this thread, could clarify some things...
