Stamina systems are hit and miss. Better stamina mod lets you configure it to be better, so you dont take two swings at a draugr then pant like a fat kid. It also removes the stamina cost for building/hoe'ing. Passiveforsakenpowers does exactly what it sounds like, though i highly reccomend not using the damage shield ones. So you can reduce running and jumping to a reasonable stamina consumption, especially in the mts and mistlands. A support of the mod on the nexus released a fix for it recently, since the mistlands update changed how the software listed the powers.
