The barrels were, but I dont beleive they were ever put into the full the gun turret and even if they were, land based tests are not accepted for other ships with wise to things such as accuracy, and yet they are accepted for the Soyuz which is unfair.
The reload rate was reduced to this amount to give a tiny bit of balance, but is still technically accurate. Many other top tier ships, such as all British 15/16" guns have an artificially increased reload of 5 seconds for balancing reasons. There is no reason why the same couldnt be applied to Soyuz in a minor attempt to actual provide balance.
The problem is… the only top tier ships that can actually fight Soyuz is Iowa and Soyuz. Everyone else doesnt really stand much of a chance. Sure, Yamato if uncontested can do some damage, but thats about it. Ive laid into a Soyuz in Vanguard and Rodney and barely managed to scratch the paint work, there is no way in hell that Soyuz is balanced at 8.7 and needs a BR increase if they wont add limits to her performance to bring it down to at least be on par with Iowa.
I have essentially stopped playing top tier NRB because the winner is decided by which team has the most Soyuz, that is not fun, that is not skill, that is just random chance, a lottery. I would rather play any other naval BR where skill actually matters.
and the statshark supports that, with Soyuz having an exceptionally high K/D, nearly 3 points higher than Iowa and quadruple that of Yamato, with averaging around double the K/D of most 8.3/8.0 ships and I assume a large chunk of that just comes from the fact they can actually see downtiers and avoid seeing Soyuz from time to time.
There is no argument that justifies having the best naval nation in game be the nation with the worst navy IRL AND for top tier naval to be a largely a single ship battlefield. Instead of Iowa, they should have added south or north carolina and instead of Soyuz they should have added… well, there is nothing else to add, so nothing.
Then add Soyuz and Iowa alongside ships like the Lion-Class and other similar paper ships that were never actually built. (I know Iowa was built, talking about Soyuz)
