@Narvik:
OK, you got some good an valid points, Baron.
What if Subs roll a preemptive surprise strike, and if a hit the casualty sink fast and can not defend.
Then all warships, trannies and aircrafts that survived in that seazone now roll for defense. I believe the usual defense numbers are too high, unless every sub mission is a kamikaze mission, so maybe everybody roll a 1 when defending against attacking subs. The AA gun rolls 1 against planes in the sky, so why not roll 1 against Subs too, they are under water after all. The Destroyer has no special ability when defending against subs. Then surviving Subs can submerge or continue attacking.
The defensive roll is the most problematic issue. If Subs are all alone, it works but when there is other units it becomes schizophrenic for the defending units, which defense value do they get and if it is the higher, then why is it possible to take subs as casualty?
One game System I played makes an independent Submarines attack first, until the attacker retreat his subs. Then, all the other units are going into combat.
This doesn’t work if there is many 2 hits BB or CVs, because Subs won’t be able to sink anything. And Subs becomes as vulnerable without specific rule such as no defense roll on the first combat round against subs.
Maybe we should explore the AAA comparison.
Rule Example broad guidelines:
Subs can attack with other units.
Each Destroyer and plane can roll 1 preemptive attack or defense @1. Remove Subs casualties.
Subs make their attacks @2 or defense @1. Remove immediatly enemy’s casualties.
All other units have regular attacks and defense, including the previous DDs and planes. Remove casualties. But Subs cannot be taken as casualties.
What do you think of this new way of doing things?
Does it worth to explore it?
