I have two concerns with this discussion thread…
Strategic bombing is not cost effective. Every time you go in (assuming no fighter cover either that would make it even worse) you have 1/6 chance of loss to anti-aircraft fire and should average 3 damage per bomber. So average 3 damage and 2 loss (1/6 of 12 ipc cost) - sorry that’s too easily swayed by bad dice. One often finds themselves out a few bombers for doing little damage. I’d rather use strats in combat and wipe out significant units.
Proposing 20 IPC for a unit that you want to have a 1 or 2 attack/defense value? Why would anyone ever buy one? I can buy 2 fighters for the same and roll with 3’s and 4’s.
Just my thoughts.
