Great report !!
Did you notice an increased number of sub hunting groups? Maddy doubled them with v2.0. So, except for the occasional lag, the campaign runs well isn't it? I'll follow your example and add it too.
That's an interesting encounter with the WW1 freighters. Ok. the first may be loaded with ammo, hit a sweet spot, boom! But three on the second?
The WW1 freighters I'm testing on single missions are sinking with just one. No matter where it hits. Even with Mark 10's. Are you sure you've waited enough time?
Maddy did a good job with the new sinking mechanics. Ships sink much more naturally and slowly. The thing I don't like is that most of the freighters go down with a well placed torpedo. Even bigger ones. I' not talking about a keel shot. A torpedo fore or aft creates enough flooding to sink them. They also sink pretty quickly with the deck gun.
I'm working on it. You can forget sinking a Takao with one eel...
Edit:
Forgot to mention the great screenshots!
