Here is a summary of the digest by getfun of a stream with Vlegris
1). IJN Zao, which is known to have better average stats than all other tier X cruisers, will not be nerfed. The other cruisers will be somewhat buffed instead.
2). When a new US cruiser branch is released, USS Cleveland will be moved to a higher tier, whereas USS Baltimore might be moved to a lower tier. When all this will happen is unknown.
3). IJN Katakami is not considered as an award for ranked battles. The developers are still thinking what to do with it. It might appear at the end of the year.
4). The 17th of September is the birthday of World of Warships. The developers will try their best to please the players, especially the veterans.
