This is good for low elos such as gold and silver where they don't peel as well and the adc doesn't know how to position. Go for flanks and one-shot the back line. Do not flash on the back line, use your speed and slow to catch them and follow when they flash. You may have trouble with bully lanes but as long as you can kill the back line you're doing your job. Abuse this until plat and you will be in the top 30% of players.
