Sounds not bad. Good view when in cover.
That would nerf the earlygame little bit, tho in larger teamgames mid and lategame its like with commanders, everywhere yellow cover thx to arty hits 
And at this time we have the scotts on the field. So this would not really change something. Beside we say pathfinder have to stay few sec before increase view starts.
That would mean if you play defensive on a vp you still have the same but if you attack you lose some power (aka you can't chase at guns so well, but still fight very well on fuel or vps points)
I'm just wondering, do you have problem with scott's own raw stat? Or the fact that the combination of 50 sight unit(pathfinder) + 50 range autofire is too strong to counter?
If scott's raw power is too strong in your taste,
1. Is the autofire is the problem?
2. Or the barrage is the problem?
