i added a diamond player from a game around season 4.
He helped me get out of bronze.
then he quit playing in season 5 and i wish he was still playing.
I've been stuck in silver since season 5 lol
It does help when you have someone teaching you things about this game and it blows your mind how much you don't know.
Having live advice is so much better than watching youtube videos and streams obviously.
He taught me great warding spots.
How to position correctly.
Map awareness
Chain CC
and more
but now i'm on my own trying to get better everyday.
