Oh I know there are bigger issues
And it depends what navy you ask; the term is also used for a warship armoured like a battleship but carrying cruiser armament and speed, intended to serve as a screening warship that could survive in the heat of battle.
I've missed that bit of news; what buff are they getting?
which navy is that? the rwandan navy perhaps? i know of no navy that refers to a ship with the same armour as a BB but less armament, as a battlecruiser.. or are u russian? where everything is different? the point of the BC is to be faster than a BB.. otherwise whats the point? make a meat shield? a BB does that already.. how do u get speed by removing weapons but keeping armour? that is a weird set of physics since we know the most weight comes from the armour
theres a thread on the proposed balance changes by ggthemachine (the guy in charge of balance)
The German Navy actually; whose BCs were far more successful that the RNs, because the RN kept adding their BCs to the line of battle, when they weren't designed to be there.
The purpose was to act as a screening ship during fleet actions - the real killer in WWI era naval battles were torpedoes, so admirals had to take care to keep the enemy destroyers at a distance. Having a screen which could stand next to the battleships in the heart of the battle, and also with smaller guns (which therefore had a higher rate of fire and traversal speed) was highly desirable.
From wikipedia, because I'm lazy: "By 1911 Germany had built battlecruisers of her own, and the superiority of the British ships could no longer be assured. Moreover, the German Navy did not share Fisher's view of the battlecruiser. In contrast to the British focus on increasing speed and firepower, Germany progressively improved the armour and staying power of their ships to better the British battlecruisers. Von der Tann, begun in 1908 and completed in 1910, carried eight 11.1-inch guns, but with 11.1-inch (283 mm) armour she was far better protected than the Invincibles"
