Noob Advice from a Noob
I'm a bronzie, so I'm in no position to give actual gameplay advice. But, as in previous post of how to improve, I can tell you things I've made a habit that has improved my own gameplay. Things that have brought me from a 22% win rate, to 53% (global across all seasons is still only 44 at the moment), things that have increased my KDA across all champs I used (in ranked when I'm not experimenting).
Advice of the Day - mute the enemy team when match starts. There's absolutely no reason that you need to communicate with the enemy team under any circumstances.
Doing this has improved my gameplay in not being manipulated by trash talk and personal vendettas.
-tee you'll see mistakes you made.
