Tittle. First point. I took the left route and killed genji. 4v5 game. Lots of poke. No space taken. Rotate. Can’t break sigma shield. Can’t climb to balcony because genji got back there. Rotate back. Eliminate genji again. 4v5 again. Lots of poke again. No space taken again. Rotate again. Sleep sigma. Sigma wakes up and walks straight to me. I die. Second point I don’ even know what to mention. I drop down from mid plat to gold 5. Half of my games (50%) are like this. Thanks.
