This game is very new player unfriendly, but if you are willing to put in the hours to learn it can rewarding. You are probably gonna be getting your ass handed to you for months even if you start basically studying the game like a subject.
With things like shooters a lot of your skill set from one carries over to another, and raw mechanical aim is a huge portion of what makes a good player. But in this game its almost more of a knowledge based game in both and air and ground.
For air you need to know at least the most common enemies you will be fighting, their strengths and weaknesses, and of course your own planes. How you should approach each situation, depending on energy, how many team mates or enemies are around, and of course how to set yourself up with those advantages.
In ground a good portion of how well you can do in a match is down to map knowledge, knowing all the good spots, how to move to them, when to move on, how to read the minimap and flow of the match to make those decisions. For aim its not just good enough to have good aim, again you need to know a good portion of the vehicles, where to aim, where to aim when you have different ammo, where their ammo is stored, how to shoot a vehicle at different aspects. I still throw terrible side on shots that get me killed because i forget and aim too center or too far back to hit ammo and that gets you killed most times.
If you are just interested in air I’d recommend picking up a cheap premium of a plane you are interested in around 3.0-5.0 BR, these are pretty safe/fun BRs to play, you stay out of seal clubber range, and out of the people that love to play their late war super props. Learn how to play that plane, and every time you die to someone remember what plane that was, go do some research and figure out what you did wrong and how you should have approached that situation differently. If you start playing realistic you’ll have some time while you climb to look at planes too and after like a a week or 2 of doing this you should be considerably more confident than you are now. There’s a lot of good content creators that can help you for air.
For ground its the same thing, except you are learning tank weakspots and where to shoot in different aspects. But learning the maps, how to posistion etc. is going to be quite the learning curve, most players don’t even think about ground in that way tbh. My enjoyment on maps I know how to play is much greater than on maps I have no clue what im doing.
For learning this stuff watching these videos can give you a good base, and give you the tools to know what good posistions look like on maps that aren’t featured here, and of course if you want to do something different you can identify what makes a spot good.
There just isn’t many content creators going over stuff like this, I like this guy the most. You have 2 other options but the content is either severly limited or outdated.
