I'm not talking about Ranked, but early game in pvp. The Vi's skills can make you hunt everyone in the jungle by running fast, and ganking, hiden in the bush, loading you "q" and free it on an enemy and kill him before he can fear the fight. The but here, is to run behind a champ with Ghost, in depth is slowing you, you can continue to hit him with the passive "w" and hurt him a lot, more and more during the fight, and if you are in hard situation, your "q" and Ghost will save your life.
