Playing against Vi
How to counter and exploit weaknesses
Her R is unstoppable but you can prepare: shield, heal, or Zhonya's when you see Vi charging toward you.
Her Q charge is visible and audible: side-step or Flash when she releases Q.
Vi is squishy if she builds assassin: burst her after she uses R.
Her Q can be interrupted during the charge by knockback or created terrain (Anivia wall, Trundle pillar).
