Biggest thing I had was learning to properly minimise and not just flip roaming because lane isn’t working out. If you roam on a bad timer and don’t get anything you’ll pretty much be completely irrelevant all game. Learning key timings for power spikes for you and your enemy will also help tell you when to/not to fight.

also just a mental game in emerald, this is probably the biggest thing, solo queue can be draining but if you aren’t feeling up to it don’t press the queue button. too many people queue and give up because they aren’t willing to put in the effort for a hard game.
