With the reduced damage potential, SBR’s on a $3 IPC territory get skewed.
With an AA present, the average is that the Allies will take $2.5 IPC of damage for an SBR against a $3 IPC territory.
(1 in 6 times $15 value of a BOM)
The defender actually takes LESS than that on average since 1 in 6 is ZERO damage, and if that fails then 2 in 6 is $1 or $2 in damage, with a max of $3
And in that circumstance, if I get your BOM, you just lost 5 times the maximum potential of the SBR.
Over the long haul, I WANT the Allies to SBR FIC or India if I have an AA there… they waste their bomber on an attack that is slightly less than break even long term instead of supporting counter-attacks against my Japan forces
Remember, SBR’s are BARELY worth while long term when the territory IPC value is $6 or greater. Reduce that top end potential damage, and they are a losing proposition.
