All I have to say is that the new sub IS extremly much better than it used to be.
-No auto-death due to a single fighter/bomber -> A LOT safer subs
-They cost 6 IPC. (25% reduction in price)
-Without destroiers, fleets may be extremly wounderable. Examples of battles:
2 subs versus 2 Carriers 4 fighters. Fighters cannot defend and the subs fights only the 2 carriers which fights with 2 twos.->
The subs got opening fire-> sub advantage. And they can destroy the entire fleet with 2 simple subs.
-Another issue would be ‘kill submarines’ or protect your ‘transports’. Can you do both? Not neccesarily, as
3 transports protected by 1 destroyer would be a tasty meal for fighters/bombers
-One sub versus 1 destroyer and 1 transport. 50/50 fight. However:
if you loose, you lost 1 sub. If you win you kill a destroyer AND a transport!
Conclusions: Subs can strike down BOTH unprotected transports AND poorly defended transport!
-3 subs at defence versus 1 destroyer, 2 fighters and 1 carrieer.
Autowin for the attacker? Not neccessarily.
Lets say that the subs kill 1 unit and the ofensive player kills 2 subs. The attacker won the battle?
Not so fast? What do you do? Take out the destoryer and leave 1 carrieer to fight versus 1 sub? Not a god option is it.
Do you kill your carrieer and keep on fighting with 2 fighters and 1 destroyer? This attack is in no way a risk free auto win battle. You risk loosing everything with only moderate unluck. In this senario it is somewhat under 50% to loose your carrieer,
and the fleet remain is one single destroyer, which is a poor defence for your transports.
Ok, Uk will probably seldom buy subs, but:
As Italy i would love to buy a sub now and then. Whenever a british or US navy comes close, I can strike first!
Often as italy you know that your subs cannot be striken down in defence there. And ofensivly subs is the best buy. You can kill whatever tries to come close.
If japan dont build destroyers, US should build a few subs just to potentialy wreck havoc.
Germany might build a few subs in the beginning cuz I doubt UK will be able to strike down their navy in the first round.
