This build feels a lot like flicker strike, you kinda just let it take you where it wants to go and get the loot later. It destroys maps even with delirium and affliction. However, it's really bad on any bosses that require precise movements like Maven or Sirus. I did all four watchstones on this character, so it is possible (6 portals with Maven though :))

I think this build might be better on something like Occultist, I made an assassin purely because I had a trickster leveled and didn't want to relevel a new character.
