orange whale...
my recommendation would be to start a career in 1943 or 44, go to any BF grid and await contact with an escorted convoy. when you manage to make such contact try and sink at least
one merchant and escape with your life... after 1943 a smart skipper wont even go after convoys anymore and will instead seek out lone targets of opportunity.
GWX2.0 has nailed the historical accuracy of crew experience when it comes to attacking submarines. in 1939-1941 the allies had no idea what they were up against, but in 1941-1942 they developed a skillfull ability to sink subs... by 1943 they are quite good at it, they knew how deep the subs could go, they knew where most of the subs were most of the time, they knew where you were headed, the allies had so much information regarding your abilities they almost knew what you were going to do before you did!
after 1944 the survival rate for even ONE mission for a sub crew dropped to nearly zero.
remember... from 1939 - 1941/2 YOU own the ocean... the allies fear YOU... not the other way around.
