The confusion seems to be in you’re holding back naval ships for naval bombardment. The advantage about scrambling planes is that it forces the attacker to commit all their naval ships regardless if they want to or not. That’s why it is sometimes wise to scramble in a losing battle if the enemy is relying on bombardment for victory. The easiest situation would be when Japan invades the Philippine islands. If Japan was so aggressive that all they brought was two infantry with two cruisers as example. I would scramble the fighter in that situation because while I will lose the sea battle, if you choose to invade the island after the battle, you’re doing it without naval support which gives my defending infantry a better chance at winning.
WHy in ALPHA +2 are there 11 German infantry in Germany?
There was some concensus among LH and those playtesting Alpha +1 that Germany was underpowered in the land attack into Russia and ran out of steam before capturing the victory cities more often than not or attaining economic parity (also why Germany and Italy got more NOs). The desire was to provide some additional land units that could keep up some momentum.
