I don't know, if you actually compare Phantom Jobs to lost actions, they are worse in every way except for a few minor things.

Pros:
  • Neat interactions in the forked tower
  • Non-consumable

Cons:
  • Not customizable or flexible. You pick one job and thats it, no mix and match, no synergizing abilities...
  • Only minorly changes gameplay. They only have one or two actions per job you actually use and sometimes none.
  • Weak compared to lost actions. The way you could combine these to make nutty builds was insane and so fun. Still to this day I can do more damage in Bozja AS A TANK than I can as in any DT content.
  • Outside of forked tower, there are only a few ones that are actually useful. Why would anyone play monk?

Looks to me like this was a major step in the wrong direction.
