The Moscow is finished. The only thing that can help it is a total overhaul of its stats. The GL needs a shorter reload time. All its cannons need accuracy buffs. It needs more missiles to even keep up with any of the newer battleships.
The grenades is the source of moscow strength and weakness. It's just so so bb despite having high dmg. Dev needs to improve grenades accuracy and speed to keep up with faster ships agility.
I have a question for you. You have a mw press account on which you have everything and get everything new. If you stop using RU-vid now, will you lose your entire account or will you no longer receive anything new?
It had it's times where It was somewhat decent, but always surclassed by other bb's like Ageis or other ships, the only thing It was really good for was countering enemy submarines in close range combat.
