I'm telling you that it's backwards.  Limiting SR to 2 per day encourages LR more because you can LR as much as you want without any limit or penalty.  Makes no sense because ALL classes benefit from LR while only a few from SR.
So, it literally makes no sense to SR.  None.  It's ONLY benefit is convenience - 1 button click for a half-butt heal as opposed to a full heal for 10 seconds of game time.
