More Issues (most fixed with mods):
Type VIIB (and some say all subs) sinking when you go below 75m or so unless using at least half speed ahead (not good when trying to run silent with angry DD's above). (havent tested for sure if any mods fix this for sure).
Grammaphone and radio buttons missing. (Mods fix this...but also change your key commands...not sure I want to do this).
Navigation sucks (trying to manuver while in Reverse is a challenge) due to lack of a "clickable" 360 degree compass (fixed with UI mods).
AI DD's still pretty dumb (mods to fix this)
Campaign requirements are very unrealistic. For example having to sink 5 warships a 1 carrier as a goal. A Uboat would rarely engage a battlegroup (no real mods to fix this).
So it seems MODS fix a good deal already (OUTSTANDING JOB MODDERS!!). Cant wait to see what SH5 will be like a year from now

I still refuse to give UBI a bye on this.
