Currency use on Passive Tree

Hey Folks

One idea popped into my head yesterday while watching the 0.5 reveal.

There are so many options to optimize gear with crafting / trading etc. but there is really not a lot going on with the passive tree.

What about letting us use currency like Divine Orbs etc. to reroll / alter values and abilities on passive tree notables / keystones etc.? This could act as a form of currency sink too to counter inflation..

Imagine getting really lucky rolls. Now this specific character allows for a completely different experience.

You think this could he fun?
