I understand how frustrating Repair Critical can be, and I wouldn't mind a price nerf on the ability. But at the same time it is a part of the overall asymmetric balance; USF vehicles (except Stuart) are more frail HP and armor wise than their counterparts in other factions, while the USF is also designed as a mobile faction that dominates the sides of the map and can converge on the middle with smoke and other abilities.
Just like snipers are less effective against Soviet and HMGs are less effective vs Ost, AT snares are less effective vs USF.
