Yes, but those are both
stunts instead of powers. Powers are explicitly more powerful than stunts, and one way they're more powerful is they don't have the restrictions that stunts usually do--compare Sex Appeal (target has to be attracted to you anyway) to Incite Emotion for Lust (Works on everybody and is a skill replacement).
As I've said before, I'm in favor of limiting AFSA to just physical defense.
I guess we have different rubrics for what's unbalanced or overpowered. To my thinking, the best that AFSA can do is move defense to the skill cap--while there are other stunts and powers that would instead let you defend past the skill cap. And if you're getting the biggest boost out of AFSA, that means you're not very good on offensive options, so your abilities are inherently limited. On those characters, it just means it's harder to beat you, but you can't really beat back.
I can't think of any off the top of my head, but are there any powers in the YS that manipulate the skill point economy like this? (replacing or moving trappings to another skill?) Or is that limited to stunts? I'm not saying that you CAN'T do it with a power, I'm just curious to see if anybody knows.
Kind of. Incite Emotion, for example, can lump seduction rolls (usually Rapport) into Deceit. It also moves mental attacks into skills that don't normally have them.
The True Faith powers tend to let you use Conviction for a lot of things it doesn't normally do.
