You average 4.4 CS per minute as Mid; Gold players average about 5.8. 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.
You spend 11% of your games dead. Late deaths cost a minute each; when a fight is lost, back off and defend rather than adding one more death to it.
5.8 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: 3 wins in 5 games (60%). 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.
