It's only temporary, as mentioned, how to respond in a crisis when their powers are gone is important.
And writing Veino, an empath whose uses the Force to keep it in check and suddenly can't, is very fun. It's breaking him, slowly and surely driving him mad. Everything he had confidence in has been stripped away and he's not sure who he is anymore. He's half-mad at this part, already. So, it's a fun thing to explore. I get to torture him than I've had chances to do so before.
And if a Force user is useless without the Force, they've been lacking in their training.
