Im in my 60's with pulverize build. You're going to cycle through several weapons once you're getting sacred stuff anyways. Then again, when you're replacing everything with ancestral. You want it on your weapon to get the full effect, also. Its kind of ass backwards, as the Aspect will always be powerful, but your Paragon is going to be the main source of power. So even if you only ever found a 190% after using this 200% one - you wont notice the difference in that, but you'll notice a difference in a weapon upgrade. (if that makes any sense)
Im pretty much just following
Maxroll's Pulverize guide and.. I can punch well above my weight currently. As there is no need for me to swing as high as I am other than getting a miniscule amount of more exp on the finishing Glyph of the nightmare.

As a side note - Ive been fretting seeing everyone get uniques all this time. Im pretty sure their drop percentage shoots up significantly in the 15-20 Nightmare range and higher, while also being 62+.
