First, I had to miss a couple of CS because I couldn't reach them, despite being right in front of me. Then I almost lost several trades because I couldn't walk backward so I had to stand there and take free poke from the enemy. Everytime I went in for a trade I couldn't escape. It was like my minions were working against me.
This happened so manyl times during the laning phase that it cost me my flash and wasted all my potions.
I didn't die, but it felt pretty silly.
