Warwick excels in the lane phase with excellent sustain and his Q's unstoppable effect, making it easy to gain advantages even without high mastery.
When playing against him, deny early kills to stifle his growth, and consider strong counter champions like Olaf, Sett, or Kennen.
His high lifesteal and global movement speed passive make him very threatening even at low health, so be wary of unexpected kill opportunities by using anti-heal and ally support.
