Her early game Jungle power is a force to be reckoned with as she dishes out a lot of damage in any duel if she manages to land all her abilities. Her Denting Blows W allows her to tank with ease too.

Very good objective control and sustain due to her Passive and her damage. Can easily get her team an early dragon lead, after successfully ganking a lane with her Vault Breaker Q.

Her Ultimate Cease and Desist R can allow her to focus a target down, which has two uses depending on her role in the game. Either she can use it to peel someone off her carries, or she can use it to get to a high priority carry (like Vayne for instance).

Pre-6, if Vi misses her Vault Breaker Q when trying to gank a lane, she will have nothing to follow up with. She will be over extended and may even die for it.

Her kit allows her to go in like a champ but she will have no way out after that. If she goes in too deep, she can easily be killed, which will translate to easy objectives for the enemy team.

Falls off during the late game due to all the enemies building defenses. She is then left to either peel for her team or look for flanks in order to assassinate the enemy carry (probably at the expense of her own life).
