I have 0 SP invested into Complete Rest because well, don't really need it and the only reason I bring a PP battery with me still is just for those down times when there isn't enough fight time to build a good amount of Voltage to recover on reset and I've spent a bit more PP than I wanted along with the little amount of V's I did build isn't a good enough recovery so it fills in the gap.
I'm assuming the rest of what you're talking about is for classes subbing Lu which isn't much concern to me because I personally don't aim to sub Lu anytime at all.
