Cross-Map Plays
You repeatedly missed the chance to answer enemy pressure on one side of the map by making a play on the other side, like when you took Krugs instead of turning top for the K'Sante pick while Dragon was being taken. The big habit here is to treat the map like a trade board: if you can't contest an objective, immediately ask what free kill, tower, or camp you can take elsewhere before the enemy cashes in. That keeps their lead from snowballing into tower pressure and jungle control, which is exactly what happened when you stayed on the wrong side of the map too long.
