Assassin/Ninja What is generally better for acrobat or assassin, tstack or spell?

I just want to know which one is better for a more endgame build

 

Sorry, what's tstack Assassin (If you didn't get that, it means that don't use it Idk why you'd use it >.>)
Uhm, Spell Acrobat 100%
Only case of Melle is Hmelle Shadestepper or Hybrid Shadestepper

 

tierstack assassin is nonexistent due to bad damage and short range
If you want to melee, use heavy melee with shadestepper

 

Tierstack Inferno gets about 100k consistent DPS but is so much more clicking and is so much less fun than heavy melee which can dish out 2 million damage quakes

The ability tree is a mixture of all three archetypes
