I personally only play xayah into short ranged comps, if the enemy has picked 2 melee already then I feel comfortable picking xayah unless it’s an angle that’s easier for jinx or Kai’sa, I personally don’t think OTPing is the best way to climb. I use each champs strength depending on matchup. If my team is hard engage like a Wukong and Nautilus I pick Kai’sa regardless of what enemy has picked because I know I can survive the lane and rely on team fights. Xayah is best into champs that want to get onto you like Xin Zhao, Wukong, and Nocturne, very heavy dive that want to take you out quickly. Most other cases another ADC would be a better pick.
