I’m not disagreeing with the idea that the version of Regen proposed is worth less than Regen with Costs Fatigue… just with the use of Always On as the model for the extra limitation. AIS, I think Nuisance Effect works better, since the drawback is fairly minor, and the effect is not “on” in the normal sense of the word unless energy is being burned by it.
