I did the arithmetic in another thread but it's already possible to one-turn-kill any enemy in the game that's susceptible to Implosion, regardless of mechanical resistance, if you can land an Expose Weakness. That's probably powerful enough. Besides, the TK Punch and Electrokinesis and Electrokinetic Imprint all benefit quite nicely from empowering.

Yes, I remember the cryostasis combo thread, and have used Expose Weakness on some hybrid psi builds, I just think the biggest ability of Psychokinesis should actually get to shine outside of complex combos using abilities that have large cooldowns of their own, you already need a proxy set up just for the ability to roughly do what it's supposed to.
Allowing the new tools of Expedition to shine favorably on Implosion would do that pretty well.
