The idea is to make Force Shock and it's morphs behave like Fatecarver skill from Arcanist class, but instead of casting a prolonged beam, that damage all targets in it's path, cast a breaf beam with decreasing damage for each target it travel through. As for morhps: Force Pulse could offer less reduction of damage for each target hit. For Crushing Shock it would be ideal if the ability will still target only focused target, and not a free aim like Fatecarver, so it could interrupt only focused target, perhaps with even more reduction of damage for each subsequent targed.
