I disagree. FP can be used for physical Extra Effort, and for long-distance travel such as h*king or swimming, and for the effects of various forms of deprivation such as food, sleep or hydration, as well as for powering most supernatural abilities (some may be Limied to ER only).

For this reason, ER is distinct from FP, although I agree with the reasoning of the RAW ruling for why ER shouldn't be cheaper than FP.
