Patch 5.6 will have many balance changes.

 The Q&A said the Montana and Iowa were mentioned to be getting buffs. I saw this on reddit.

A worthy and informative thread.

Here's the link for those who are interested. Q&A

It just says that the Iowa and Montana will be buffed in nearly all characteristics. A previous Q&A specifically mentioned accuracy improvements too.

I expect more Atlanta love, and hopefully some Sims love.

The sims needs it. Any love for Yubari yet?

I have not seen any, but rebalance seems to be the name of 5.6.

The Iowa is such a turd it needs the acc buff to be even remotely competitive. 

[Jarkorsis 92]

Sims is still losing at least 1 turret per match, so needs all kinds of help. (T7 torps would be nice instead of T2 and T6)

That's how you roll out patch notes.

Unfortunately they buffed all the relatively good ships and left the shitty ones untouched, except Furutaka.  The huge AA buffs are a bit excessive, CVs are pretty much a novelty now anyway that's only good at punishing a shitter who is overextended.
