Yellow, I got some points that need your examination.
1) His ability to apply the Featherstone Knack to any sniper rifle, via a power stunt. I reckon that the device flaw still applies, as he needs a specific (and somewhat rare) item, but the stunt means that it isn't a unique item.
2) The Accuracy extra on the Featherstone Knack (based on
*this* , allowing him to add his power rank to attack rolls when using that power.
3) The extended Surprise Strike range. My logic went like this: The ability to SS is based on being able to place an attack precisely. Normally, you can SS within 30' (3 sight range increments for a normal person). So, as Lucian's visual RI's are x1024 longer than normal, I figured the same proportion would apply. His advantage is he can place a shot that accuratly over extreme range due to his long sightedness.
