Yeah, giving Fubuki the high-angled 10cm gun should change things for the better for the kanmusus. Historically the destroyers at Midway were more or less useless in anti-air role since they only had 25mm guns to rely on with their 12.7cm optimised for surface combat and hence neither fast enough, nor with the needed elevation to shoot down aircraft. The carriers mostly had to rely on their own anti-air guns and hence the Japanese anti-air guns only shot down two of 146 lost US aircraft at Midway. So expect Fubuki to be raining down barrages of fire against the Abyssal planes to save the day the next two episodes.
