As others have said, making it some sort of inconsequential thing (Like, say, a visual glow effect like from Afterglow for a job of your choice) is the only way this would work.

Merit WSs is a similar idea to this, except in that case you can choose 3, and that is already going over pretty poorly. Not to mention the fact that for half the WS there are alternatives that are equally powerful after factoring in compensation from aftermath effects. The suggestion the OP is making is basically if every single merit WS was on the level of usefulness of Ruinator for BST or Shoha for SAMs, where if you don't have it the job becomes severely crippled for your character.
