Anyone knows any good overall tactics, i cant seem to get it right, i wonder if theres a basic good overall strategy that you guys can share
I think the important thing is to develop the habit of testing.

You could copy a great strategy but at some point this strategy will be outdated and you will need another one.

This is my second day in the game, I have tested several things and now I am having some success against teams of my level.

Like you, I was totally lost, now I'm getting on the axis.
This topic has helped me a lot: https://www.mobamanager.gg/community/forum/topic/show/1044

So you will be independent of others, you will learn what works in the game and what does not work in the game.
Kill everything in lane and farm a support in the jungle. At least this is how you win for now
