You die 7.3 times per game (Diamond average: 5.5). Deaths hand over gold, tempo and objectives. Before walking forward ask: where is the enemy jungler, and do I have vision of this bush? Trade a kill you are not sure of for a safe recall.
You average 5.5 CS per minute as Mid; Diamond players average about 7.3. Every 15 CS is roughly a kill worth of gold. Practise last-hitting under tower, shove the wave before recalling, and catch side waves between fights instead of standing in lane doing nothing.
Your vision score is 0.77 per minute; Diamond players average 1.10. Buy a control ward on every recall (75 gold is the cheapest insurance in the game), use your trinket off cooldown and sweep the river before objectives.
You deal 18% of your team's damage to champions as Mid. Carries should be closer to 25%. Stay alive in fights by attacking whatever is closest instead of diving for the backline, and finish damage items before defensive ones.
You typically come out of lane ahead of your opponent. Turn that lead into map pressure: shove, take plates, then move to help another lane while your opponent is stuck.
3.2 solo kills per game — you win 1v1s. Use that threat to draw the enemy jungler to your lane and free up the rest of the map.
