This build gives you a chance to keep your teammates alive and your guardian shield gets stronger as your health inevitably grows. I average 2000-3000 shielding most games and my CC score is epic from maxing W first to mess with the enemy team and steal objectives, zone people away from my team or securing/helping with kills from afar. Also Swains W when it is maxed will give you 8 seconds of vision on them.. Most people back while they have vision on.. Don't let them back and you can add Embrace or Liandrys to keep them from backing while your W cools down. HAPPY SNIPING and keep crushing with Swain.
