Ao'yin is a farm lane carry who rewards patience. He has enough range and burst pressure to punish mistakes, but he still needs clean spacing before he commits to a trade. The best Ao'yin games are not constant fighting. They are controlled lanes where you farm safely, chip the enemy down, then use your big cooldowns when the enemy support or jungler has already shown.
