Assassin/Ninja Lv. 64 Assassin DPS Build - further progression?

Hello fellas!

I've got myself this fine (at least as I think) DPS build and now wonder whether it is a viable option to build DPS for further progression? If yes, what are some modifications I can make to my build on levels 70-75? (Shadestepper Assassin - decided to mention, maybe it is important)

 

Looks decent for a melee build, if it's a spell build it needs a lot of work, however. I can try making you a spell and/or melee build if you would like.

 

It is indeed the melee build, not the spell one. I would actually appreciate any help :)
I am looking into maximising DPS output, what are your suggestions regarding the build going into levels 70-80 if its not too much to ask?

 

honestly you'll probably find damage upgrades from switching away from set gear, though for the sake of recommending something in line with what i'm looking at, you can look at the visceral set for a slight upgrade to survivability and some very slight extra damage. But overall you'll definitely find way better damage from using non-set stuff
