I'm probably repeating a lot of what has already been said here, but this is my feedback after a few hours of playing this update:
-The new hulls are cool
-Improved target info is great
-I like the new missions
-Torpedos seem to pack a better punch now
-Damage decals are a nice touch
-HE shells are still better than AP shells 99% of the time. When firing at a heavily armoured target, an AP shell penetration should be VASTLY more damage than an HE shell, instead it seems to be about the same, except that HE shells will also do plenty of damage when an AP shell would bounce.
-Secondaries are still mostly useless. They don't feel more accurate. Even with modern tech, radar etc I'm seeing < 1% hit chances at ~5km ranges against destroyers using 5" secondaries, which maybe raises into 2-3% after some time of constant firing. Meanwhile the mains will hit in a fraction of the time and generally sink a DD in 1-2 hits.
-Heavily damaged ships not sinking doesn't seem of have significantly changed, it still seems to take 5 mins to get a ship downs to 50%, then about 30 mins to actually sink them.
-The torpedo warnings are a good first step, but I really can't understand why there isn't a constant highlight on then - something like the little arrows that WOWS uses would be perfect - not too distracting, but enough that you won't miss them easily like you currently can.
Overall moving in the right direction.
