You average 7.0 CS per minute as Mid; Challenger players average about 8.3. 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.
After a loss you win only 57% of the next game, versus 79% after a win. That gap is tilt. Make it a rule: two losses in a row, and the session is over. Your LP will thank you tomorrow.
Your vision score is 0.95 per minute; Challenger players average 1.30. 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 take part in 52% of your team's kills; Challenger players average 62%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
1.6 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.
Katarina: 12 wins in 18 games (67%). When you need LP, this is the pick — climbing is easier on a champion you win with than on a "stronger" one you don't.
