I was thinking about a different condition to reduced StBs damage from D6+2 to D6.
Instead of requiring “- Bombers conducting SBRs only receive a +2 damage bonus if they have departed from an operational airbase”
Interceptors can act mostly like Destroyer affecting Submarines, negating +2 bonus on damage.
When at least 1 Fg is intercepting, all StBs can only make 1D6 damage each.
That way, it can be a good incentive for interception just to reduced the heavier full damage when all defending planes duck and cover instead.
It virtually put almost all SBRs within the 1:1 break even ratio of 1942.2 TripleA SBR, which is right on the line for both attacker (need to invest 12 IPCs) and defender (need to invest 10 IPCs).
For example, against 5 StBs, a single Fg would cut +10 bonus damage to IC, that way it makes a good investment for defender since it already save the cost of a Fg if all StBs reach IC and bomb it.
It is also a way to overcome the big attacking bonus coming when there is as much escorting Fgs as there is interceptors, since it make StBs out of arms way of interceptors. With this rule, there is no need to make StBs first casualty.
About Fg escort and taking StBs as first casualty, don’t forget that intercepting is not mandatory and attacker have to divert Fg unit for a single hypothetical roll @1 from more useful rolls as an air support unit @3 in a regular combat. Denying Fg escort this ability to be taken as cannon fodder for an StB is a deterent for the attacker to use Fg for such random outcome in SBR. In fact, fighter escort main role is more as cannon fodder rather than as offensive weapon in these circumstances (as well as Fg can better be used as a mobile attack support in other combat zone).
What do you think of this trick?
It has more scope than only solving India’s IC case from japanese StBs.
