I assumed that for critical failures no.

I was more asking (mainly for powers and aoe type effects) for when attacking yourself (or your own hex or adjacent hex) might be the best option (especially if you have a defense that you want to use like a power based dodge or even an ability that activates on an active defense).

E.g. I shoot the ground in my hex then use high move and dodge scores to dodge out of explosion (and away from the nearby enemies who were behind me so I couldn't attack them or dodge their attacks)
