Assassin/Ninja Help 2.0 Heavy Melee

How has 2.0 affected heavy melee? Is assassin still the best for it?

The main part of shadestepper is marks, which are placed by spells, and heavy melee doesn't like spells too much.

Do you tiptoe around the ability tree and only use the abilities that help, like surprise strike?

Or would it be better to adapt it somehow to use marks effeciently?

 

Twain's Arc Sharpshooter is pretty nutty

 

actually you can just drop one smoke bomb on the enemy and wait a few seconds for max marks, then go in vanished with a quake or normal attack and still do huge damage.
