This small mod just changes two GMST records to set both Stamina and Magicka Regeneration during combat to 1x, rather than 0.33x/0.35x
I couldn't add health regen as the setting is set to 0.000000, sorry.
We'll see about an Xbox and PS4 version, as I did this mod in Tes5Edit, as it's a real PITA to fire up the CK to make 2 very small edits.
