The soviet navy was gimped. First off only 12 inch guns up to 91, thats kinda gimped to be honnest. Most other nations can out range and damage russian bbs.
The sn was sappose to have second longest range and damage, making it a nasty threat to all...well seems that its lacking in this.....
Now I heard there was a patch coming to fix this and some mn issues but no clue when that is coming.
