Level 60-70 assassin build

Im currently level 63 and looking for a level 60-70 assassin build and tree. I want to do a shadestepper build, but im open for changes.

 

Idk what I did at level 55-68 but this is a level 66 shade build
This is a level 60 build.
This is a level 68 build.
For those, keep in mind, they were originaly 69,67, and 68 but I lowered the level to minimum usable so the a-trees might have overused points.
Not sure how good any of those are because I had difficulty soloing Death and... who's the other of level 70's big four bosses? I think Bob?

Instead, at level 70 (swapped to Trickster)
