I honestly wished they'd buff GK sonar. Such a big ship with a very weak sonar. Maybe expand the sonar range or maybe give it more time, also I'd like to point out the secondaries. Maybe give them a little more range.
I love GK. First LT ship I unlocked when bureau was introduced and is still my most played ship in the game. Glad it finally got some attention, but you right. WG missed an opportunity with the buff. Because we all know “beneficial” that 1 minute hydro is on a BB of GKs size. Would have liked to see a hydro buff of 90sec or 120sec
GK with AL Bismarck in a full secondary build becomes a tank and brawler all in one. Her reduced damage while using secondaries is nice and her increased accuracy on them makes them really start to hone in on destroyers.
Tommy, I agree with your analysis of both ships. Montana is improved now. Agreed on GK main battery. The GK needs at least better rear firing angles or improved armor on main battery- to not get incapacitated every time they get hit, or your suggestion to upsize main battery.
It's likely one of the reasons for 420mm being the value chosen was sheer laziness, since they're porting the models from World of Warships (PC) which has always had 406 and 420s. Both calibres have their place as the 420s have higher alpha.
I would say Monty benefited the most out of the 2. If GK's sonar could had a longer duration and a .5km increase on the secondaries then I would give it to GK.
