Is this ability overperforming? Whilst activated a Bofors can withstand a direct hit from a Stuka dive bomb, two direct Stuka Zu Fuss hits, any off map artillery. It just doesn't make sense to me that 160 munis can be spent on a dive bomb and a comparitively cheap ability like Brace Structure counters it.
What are others thoughts on this?
That is exactly the very purpose of this ability.
Emplacements counter is sustained damage, not bursts.
Also, why do you think its fair that couple of hundred of menpower and few tens of fuel should be erased with single ability?
Hell gates broke loose when OKW trucks were destroyed by 300+ muni ability for comparison.
