I was just going to post this. The main guns of the Jutland are a total joke. It has all these big turrets...that are really just pea shooters. They are inaccurate at range and have such an abysmal dps that there's no point in using them in place of the secondary turrets. It is the only absolutely useless weapon in the game IMO.
The Jutland gun DPS isn't that bad, the main problem is the spread that make you miss 4/5 shrapnels
