Lots to decipher, let's see...
Kinda useless, expect maybe to quickly build higher level Industry quicker. -10% Construction Cost isn't going to cut it, I'd want at least -20% to even consider playing such a doctrine, especially with:Therworldtube wrote:
Commonwealth Doctrine (Rearmament)General Strength: Construction cost -10%, construction time -15%
This is to reflect Britain's effective repairs during the Battle of Britain, where despite the constant bombing of factories and air strips, the British were still able to restore most of the building's functions.
So basically, this doctrine is screwed against Allies. I mean, if Allies can produce 45% faster, research faster, upgrade faster, and units cost the exact same amount of resources. Meaning Allies can basically have double the army and higher level tech, while Commonwealth would have...better buildings?Therworldtube wrote:
General Weakness: Production time +15%Britain's mobilization came rather late. They really didn't go partial war economy until the Munich conference. And unlike the USA, where it can easily pump tanks and soldiers in mass quantity (which reflects the Allies Doctrine), Britain has neither the resources nor the manpower to sufficiently defeat Germany by itself.
...Like, what's the point? Axis Motorized Infantry would shred it anyways, 25% won't do much (also considering Militia would take +15% more time to produce)Therworldtube wrote:
Militia - 25% urban terrain buff,The militias of Britain were the Home Guard, where it is expected urban fighting will happen. The buff will also compliment Churchill's quote: "...We shall fight in the fields and in the streets, we shall fight in the hills..."
No argument here.Therworldtube wrote:
Infantry - 1/2 day researchPretty much what I said on the general weakness. Also didn't help that British non-motorized infantry didn't fare well in early war France, eventually leading to the Dunkirk evacuation.
You do realize that Axis Mot Inf has +15% HP, +15% Damage (plus another 15% against unarmored), +15% Move Speed, and earlier research, right? And according to your comment, the cost per unit should be lower, not that they magically get +10% HP (which, I reiterate, would be useless except maybe against Allied Inf).Therworldtube wrote:
Motorized Infantry - Health +10%I based this on the fact on the British army during the North African campaign, where it was very motorized. From Operation Compass to Crusader to El Alamein, the British army could afford to have trucks, whereas the Axis army simply lacked the oil for even the Italian navy to ship oil across the Mediterranean.
Uhhhh, sure, I guess? No-one would bother making it, not with a +15% production time...Therworldtube wrote:
Commandos - Same buffs as the Allies doctrineThe price is much more expensive, but they are faster.
Only one I 100% fully agree with. I would go as far as to say it needs a speed boost and even HP increase as well.Therworldtube wrote:
Paratroopers - Production cost -20%, -1 day researchAs the pioneers of paratrooping, including operation Biting and Market Garden, it would be disservice if I don't include this.
You say they chose quality over quantity, but I see no increase in damage. All that is there is an increase in research availability. How are they supposed to defend against armour? Tank Destroyers are only available Day 3, and take 10 hours to produce with a Level 1 Tank Plant.Therworldtube wrote:
Anti-Tank Artillery - 2 day researchAfter Dunkirk, Britain has the choice of producing their 6 pounder guns, which was on par of the PAK 38, or choose the smaller and cheaper 2 pounder. Needless to say, they chose quantity over quality.
Makes sense since Blitz and all.Therworldtube wrote:
Anti-Air Artillery - 10% damage vs Air
Rest In Peace Britain, for you will 100% fall to the Germans if this becomes reality...(Seriously, there are like no buffs to this doctrine, why would I even bother playing ;-;. And here's me thinking Allies is the worst.)Therworldtube wrote:
All of the Self-propelled ordnance - 1/2 day researchI can barely find any British development on this category.
Agreed, but might imbalance since they also have good anti-air (basically choose one over the other, can't have both).Therworldtube wrote:
Interceptors - -25% production cost, 10% damageSo pretty much Britain's fighter production is to produce as much fighters ASAP. The fact that they were so desperate and low on steel, that they constructed the Hurricane and the Mosquito out of wood, exemplifies this buff (even if an Axis fighter still has more health).
Sure...why not? This doctrine needs all the help it can get I suppose (even though early research isn't going to help because of the dreaded +15% production time...).Therworldtube wrote:
Naval Bombers - -1/-2 day research
Surface fleet part is useless, just why? No-one willingly sends destroyers to attack battleships or carriers. Increased sub damage is alright. For this unit, I would like to see earlier research (and possible increased view range) at later levels so German subs can be spotted but are still a problem to deal with (since they have Axis buffs)Therworldtube wrote:
Destroyers - damage 10% to surface fleet, damage 15% to submarineBritain, much like USA, has an emphasis on fighting submarine. British escorts were effective until USA swarmed the Atlantic with lend-lease, straining the escort vessels.
No point, only change for Allied units is earlier nukes (which the Commonwealth did help a bit, so I guess there's no problem with it happening Β―\_(γ)_/Β―)Therworldtube wrote:
As for the Secret units, it can copy the Americans.
Would like to add, there are no changes to Armoured units. This puts it at a big disadvantage to all other doctrines (Axis Med Tanks, Pan-Asian Light Tanks and Armoured Cars, Allied Tank Destroyers, and Comintern Med and Heavy Tanks).
All in all, I like the idea, but, no. Keep the ideas coming though, do appreciate the enthusiasm 
both a history of a capable secret service, and the ingenuity to think out of the box. Enigma was devised by the British, not the Americans; in fact it was an American frustration for the entire war that the British were simply better at it while their own services lacked experience after decades of isolationism. They were also better than the Soviets and a LOT better than both the Japanese and the Germans (just check out the DΓΆnitz quote on the splash screen).
