Bombers at 14 means no one buys them, ever.
Cruisers at 12 mean almost the same thing.
And armor at 6 is less cost efficient than mech inf at 4, for attack and defense.
And why would I pay 1 more IPC for a tac bomber that only fights as good as a fighter when with a tank when I could instead buy a fighter.
Time for more math! Woot.
Let us take a combined arms force, we will say 3 inf, 3 armor, and 3 tec bombers. Using TripleA battlecalc and assuming the tec bombers are regular bombers which is better for them because they don’t loose the +1 due to the armor dying, but that is beside the point.
3 inf, 3 arm, 3 tec bombers vs 11 inf win 52% of the time
4 inf, 3 arm, 3 fighters (same cost) vs 11 inf win 54% of the time
Dollar for dollar they are about the same on the attack in a mixed group, yet fighters have no restrictions like needing armor, AND they defend better.
End result is for useless unit list:
Cruiser
Armor @ 6
Tactical Fighters @ 11
