To me, escort AI is enough strong and not really a game problem anymore (except for launching DC)
But i have a little request about merchant AI:
- it would be very welcome if they could escape sub opposite direction
full speed, as it was probably in RL when a U-Boot attacked, cause actually they tend to slow down for a while before heading other direction (mainly in convoy state)...and they never accelerate! They remains very nice targets

Logical behavior should be ahead full in any direction and zig-zagging

They tend to be back original heading direction too fast also.
It's sometimes a real killing party when non escorted:
EDIT: forgot to say i'm also using Sober deck gun mod...when to much wind, gun becomes almost useless (and it's good thing) but when sea is calm...like above...
