Did not sink quickly because in V 2.0 I have created longer sinking times. DD's can still sink quickly, depends on compart how fast it floods etc. This scenario, really was not a quick sink scenario I suppose. Nice to see damage model I spent hours tooling with work properly lol as it did sink by the stern.
Yes, would have received credit for the DD but I did not, "just" the tankers. I remember a cheat I used to utilize in stock was i'd strafe the DD with AA gun or hit it with one or two shells after it was damaged by the explosion from other ships, this way sim recognizes me as inflicting the fatal blows, sometimes it worked lol. Back in the noob days lol
