Assassin/Ninja Assassin Build [Level 76]

Hi!

I'm currently level 76, and wanted to figure out the best possible build I could use. After browsing prior threads, I have a few questions:

1. Is champion armor the best offensively? (From what I've seen, people deem it the best defensively – correct me if I'm wrong).
2. Is a spellspam or melee-based assassin a more powerful one?

I'm mainly looking for a build that maximizes dps while not turning assassin into a piece of paper. I would love to hear build suggestions :)

Thanks!

P.S – I'm not sure if this factors into the builds, but my chosen archetype is Shadestepper.

 

champion set is pretty good offensively as well, use it with bobs daggers, draoi fair and other accs
spell is prob better at that lvl, but you can change to a melee build near lvl90
