How can i get better?

play AD azir jungle= FREELO

Record your matches using something like Baron Replays or Replay.gg . Analyze them. Whenever you do something wrong (like die to an enemy gank), think about what you could've done better humanly.

Here's some tips and I'm by no means a "pro" but they have helped me.

1. Map Awareness. Always watch your mini map, make sure you are constantly warding etc. (I'm still working on this one)
2. Play champions that you feel comfortable with (ALOT) don't just counter pick because the Internet told you to. I will play a lot better with a champion that I've played 20 times over a champion I have played once and picked them to counter the enemy.
3. Avoid ganks, comes with map awareness.
4. Learn the abilities of a lot of champions. If you know the mechanics of the champion you are playing against you can better avoid his attacks. For example: if you are playing against a teemo and he just used his blinding dart to poke you, then you know he can't blind you as you engage.
5. Communication is huge. Talk to your team, let them know if you are struggling or need help in lane.
6. Choose the correct time to engage. If you have an Alistar on your team and you are an ADC wait for him to do a knock up before you get close enough to be damaged.
7. Last hitting minions is simple in context but can drastically change the game. More last hits=More Money=More items.
8. Recognize the fight or flight situations. There is a point in a game where you feel a shift, you feel powerful. You won't even have to try and see it. It will just happen with items. Once you know you have the power, don't be afraid to use it.
9. Relax and have fun. Constantly worrying about a KDA is stressful. As long as you are helping your team in fights and taking down turrets, you are doing just fine!
10. Biggest problem with league is a lot of Toxicity with other players. If you have a teammate that is just feeding or afk or being rude, ignore it. Just play YOUR game. Report him afterwards and he will get what's coming.

Hope this helped somewhat. And good luck on the rift (or Aram) if that is your cup of tea!

Little late and you out rank me I'm only Gold III. But I think I can offer some advice that could help you win more games. Your champ selections seem to be all over the place. Might want to pick a few champs and a role to main and just get really good with them. At a certain point being a jack of all trades isn't as good as knowing exactly how to make a big impact with whatever role you main. Looks like you have a ton of champs and only a few rune pages, I think you'd benefit from more rune pages with stuff that is specified to certain champs and matchup's they will have to deal with. like a Tanky top when dealing with AP champs AD champs runes for when you want to be aggressive or when you just want to survive lane. Are you always counter picking? Or do you just like playing a ton of champs? Lastly Wards win games don't forget that even if you're behind buying a ward is always a good idea ( my biggest flaw IMO I don't ward enough). Well good luck hope some of this might help you!
