Aloha,
Firstly, welcome to World of Warships and I commend you for doing research! That is after all, one of the first keys to success in this game.
Secondly, may I remind our community about the forum rules. Some of you need to re-read them.
Thirdly, and I mean no offense by any of this but, you only have 83 battles in Random game mode. Which means that more than likely a lot of the early game access items have not been opened up to you as of yet.
Keep grinding forward.
Pick one line and grind ONLY it until you think you have a really good understanding of the mechanics and game play
Take advice from people with a grain of salt
CVs at the lower tiers are more a pest, but IMO its good (though I know it is annoying) to get primaried with the tick damage as often as you might in lower tier battles
That being said, think of things in this aspect, it is teaching you how and when to use your DC, how and when to use your RP etc. This is important ESPECIALLY at the later tiers as your micromanagement of your HP is MUCH more important depending on fire and flood damage
And it teaches you to keep maneuvering, when to sector your AA etc
Some players don't learn this, EVER.....
Most people will not recognize it, but we are still adjusting and balancing CVs (almost every single update for the last 6 months has had adjustments to them) and we are still doing more
Division up with other players, try NOT to play solo, you will learn FAR more and your experience will be FAR BETTER. If you want to division up, PM me sometime in game, I will gladly division up with players, assuming I am not already in a division.
Contrary to what some say, signals, capt builds and upgrades make a HUGE difference in surviving a battle (for those of you that are naysayers, try running your ships without them for a couple battles and see the difference, assuming you run WITH them regularly)
That being said, at the lower tiers, don't use them, hoard them for tier VI and up
Mahalo,
