If I have paratroopers I routinely have 3-6 bombers anyway. So you’re really looking at something like this:
Germany attacks Norway with Infantry/Bomber - +3 IPC
Germany attacks Finland with Infantry/Bomber - +2 IPC
Germany attacks Gibraltar with Infantry/Bomber - -5 IPC from England (NO lost)
Germany attacks Brazil with Infantry/Bomber - +3 IPC
Germany attacks Madagascar with Infantry/Bomber - +1 IPC
Germany attacks Ukraine with Infantry/Bomber + Armor from somewhere else - +7 IPC (+5 for the NO, +2 for Ukraine.)
Net: +3+2+3+1+7 = +16 IPC for Germany that round
Potential -16 for the allies (if they cannot reconquer all that land.) At the very least, the allies are now scattering units and resources all over the map attempting to reclaim everything they just lost.
Second Scenario:
Here, for instance:
Germany attacks Russia with 16 Infantry, 2 Artillery, 16 Armor, 6 Fighters, 6 Bombers and Russia defends with 26 Infantry, Artillery, 15 Armor, 4 Fighters (all realistic numbers.)
Germany has a 55.3% chance to win but that win does not include ground forces, only bombers left most likely. Russia has a 43.9% chance to win with most likely nothing but the Fighters left.
If Germany had Paratroopers, they would have +6 Infantry and their odds would change too 92.3% chance to win with 7 Armor and Bombers left (assuming you took fighters as casualties before Armor) and reducing Russia’s odds too 7.4% odds of winning.
It’s a massive change in the odds, roughly 37% swing just because you had Paratroopers and could drop those extra few infantry off for the major battle.
Sure, you could have spent the next 3 turns out building the Allies defending Russia and then attack, but that’s three extra rounds where you could have been snafu’ed by the dice somewhere.
Scenario 3:
Germany has Paratroopers and the threat of those 6 infantry, 6 bombers causes England to keep extra manpower in England. This slows down England’s progression and allows Germany time to build up a stronger defense. Without the threat of an aerial invasion of England, England would have been able to move more units into France faster and been able to do a joint amphibious and ground invasion of Germany before Germany could recover and build up their defenses after a battle went sour.
That’s just three minor scenarios. Each of the three cannot be done by Heavy Bombers or War Bonds or any other tech. Don’t get me wrong, the other technologies are great! I’m just not convinced, PERSONALLY (and this is a personal opinion, I’m not trying to tell anyone they are wrong to think other technologies are better, maybe they are for their style of play), that paratroopers are by far the best technology in Anniversary so far.
