WOWS spends a lot of time working on the authenticity of the ships but one thing that I found missing in game for the era of the ships is that the US were using gun aim directors which resulting in salvo firing of all the guns at the same time, while, for example, the Japanese were using aiming with coloured shell placement, so used ripple firing. Ripple firing here, I mean that each gun is fired when ready. In fact there were occasions where the fleets recognized their opposition based on the firing type of the ordinance.
Any chance this could be better represented in game
