League of Legends (LoL) Question: that will help us all

I don't know how I used to live without knowing about this app https://bollywood-casino.com/game/32-cards-live/ . It is the newest card game that brought me a lot of fun and brought me out of depression. At a time when I didn't know what to do since I had no friends, this game allowed me to get positive emotions and kept me from getting upset.

Just be a beast.
I know it sounds simple, and it is simple.
Play smart, help your team, and carry.
Map awareness is key, very important.
And you can carry from support, you don't have to play certain roles to win.

1 - It's quite common to lose games when you're starting playing rankeds, as usually ranked games got higher mmr (according to data from sites like lolking and op gg). Simply you're going for games with players with higher mmr than you're used to play.

2 - From what you're saying you're playing mostly top laners/junglers. It depends mostly fo team composition, what team need you to do: split push or team fights. Playing safe and being not greedy always help, also roaming in mid game from top is some idea to carry.

3 - As LevasK said, could you explain what you mean?

4 - Being kind, no flaming others players always help from my experience. Giving advice, but not being conceited - in other means communication with team.

1- It's common to lose games in every level, division and tier of play. Remember that, even if you are winning only 50.1% of your games, you are still progressing.

2- This question is way too vague/unspecific. (Imo in lower levels of play, just try to get cs, then look for kills).

3- Please elaborate.

4- Try to be polite at all times, don't order people around, but suggest things to do like: Hey guys, lets group for this dragon.
