In Patch 14.18, however, one champion is currently struggling to find any kind of success in the top lane, even though they are one of the most played picks in the role.
Vladimir is currently holding the third-highest play rate, but is one of the worst-performing champions in the top lane, according to League stats aggregate https://u.gg/lol/top-lane-tier-list?rank=platinum_plus. He has an 8.6 percent play rate with over 200 thousand games played globally with an abysmal 47 percent win rate, placing him in the bottom five for his role as well.
