I understand your thinking about SaT. I get the fluff, but for crunch reasons there's just no way this power will ever be necessary.
Once I have Rea 9, I'm pretty sure the fastest guy in combat, except for hot-sim rigged drones. Let's say I have 14 initiative and 4 IPs. Why would I spend 1.5 powerpoints to get to 17 initiative in a 2nd combat round. My enemies are already either dead or suffer initiative modifiers due to wounds.
If this is the icing on the cake, it is a barely visible, but expensive icing, about a micron thick, and the chef has to tell everyone about it, toherwise noone will notice.
