Three simple things to progress in ranked BR

Use your mic for progressive communication - Not offensive nonsense
If you are using a mic, don't wait with using it until you die, just to offend your teammates, telling them how useless they are for not being able to read your mind as you took off alone, engaging a 3-player squad. Use your mic before that, to communicate with your teammates, then perhaps they will actually join you, wherever you go.

You are not the leader by default, especially if you don't communicate
Don't criticize teammates for not following you if you didn't communicate your game plan. If you try to point out that someone is useless for not following you, jumping headless into a squad, just to die alone, then you are one lost individual that needs to buy a very big mirror, because YOU were the useless one for doing that.

There's a reason why Apex Legends has two BR game modes
You don't have to jump hot with 6 other squads at Fragment when playing ranked games. It's actually quite dumb, since you are more likely to die within 12 seconds, than to to get anything out of that game. You will simply just lose ranking points. Don't forget that there is another great game mode if you want to play crazy and jump in the middle of mayhem.

The game objective is not to run, it's to win
This might come as a surprise to you, but the game objective in ranked BR is actually not to run as fast and far as possible. It's to be the last squad standing and that's what gives the most points. it's of course great to also kill a few players or even entire squads. But if you stop your headless running for just a second, look around, and try to figure out where enemy squads might be, there is a good chance that you will get to choose your fights. Because if you spot the enemy before they spot you, then you will have an advantage over the enemy. 

By running around like a headless chicken, looking like an extreme case of ADHD, you will be spotted and shot at. That's quite simple, isn't it?

Be smart, not selfish and ignorant
And last but not least, when you land, don't go for the same crates and loot as your teammates and try to communicate so that you know which ammo they are using and vice versa. That way, you can help each other to gear up properly, very fast, instead of being totally mindless and ignorant, not caring at all that your teammates get geared up.

But let me tell you a secret; If your teammates get properly geared up, they will be able to assist you better in fights, perhaps even to save your a** at some point.

The three simple things that will help you progress in ranked BR
All these things can be boiled down to three simple things that many, many, many players need to think about, and that's 1. caring, 2. communicating, and 3. behaving,

If you mind these things, you'll have much more fun and you'll progress much faster.

Now, after reading this, and if you still feel that you don't care about these things, then please stick to pubs and stop ruining games for people that care.

Thanks!
