I don’t like ICs either…and I believe India to be an average play at best and S Africa sub average…but thats just me… :)
However,
You can effectively do either and still have a fleet with little loss of momentum in Europe.
UK 1:
Build IC. Save 15 $…collect about 26-27$
US 1:
Build AC & 2 Trannies. Leave existing tranny at home. Ftrs to ECan/UK.
UK 2:
Build 3 Trannies. Build 1 Inf in UK. Build whatever else you want as ground units @ your IC.
US 2:
Move AC, 2 Ftrs & 3 Trannies to NorthSeaSz.
Summary:
At the end of round 2 you have AC, 2 Ftrs, 6 Trannies.
The US has enough troops to fill their load.
The UK has enough troops to fill their load as well.
You have about the same size fleet as you would otherwise have in total. Perhaps down 1 Tranny.
A UK 1 buy of AC & Tranny, rarely if ever moves on UK 2 anyway. So you end up in the same position after UK 2.
You sacrifice a potential UK 2 attack with 1 Tranny load which usually can’t occur anyway…or a 2 Inf dump in Finland. Same point applies to US 1 tranny (which usually pointlessly unloads 2 Inf in UK anyway).
You still have only 1 Capital ship and have simply shifted the investment from UK to US.
You still can attack/dump 3 US tranny loads into WE, F/N on US 2.
You can still dump 3 UK trannies into WE/Africa on UK 3.
Thus, a UK 1 IC build does not negate fleet action, and in fact, has marginal affects on Europe in the early game. This is not a reason to not build an IC…there are other reasons…but this one is easily ‘solved’.
Indeed, you even have the advantage of a potential freedom to use US Ftrs against Japan at Pearl on US 1 without having to worry about covering a UK 1 AC & Tranny. If the UK Ftrs go to Karelia on UK 1, you can use one or both to non-com land on the US AC on UK 2. Thus, when the US moves its fleet on US 2, you still have air cover for it. It all depends on whether you can/choose to risk US Ftrs against Pearl…even if you lose 1 or both, you still can send 1 or both UK Ftrs. Not that I am advocating this…just it opens an option if circumstances are right.
