I hope they do not nerf voli. There are several champs out there who can directly kill voli in a 1 v 1 mele with him, yi, trundle, xin zhao, jax, maybe shyvana, probably warwick. When I am voli and I am forced to duel with these champs (Except yi, he is really tough to deal with late game 1 on 1), I have to kite kill them. I E, then move away some more, E, move away some more, slowly wearing their health down. Then I just ult and bite to finish the kill.
unfortunately with yi I cant do this.
Anyway, back to my point, for lower elos, you NEED voli, to help you out. His ganking power is great, and he is able to shut down games early. I was a really good Jax player, (and jax is honestly more powerful than voli 1 on 1), but I found it difficult to carry a team of 4 idiots and just me. Why? because all the adc or anyone else needs to do is flash once away from jax or get out of his Q range and kill him. There are lots of ways to kill jax.
Jax will stun someone, but then they can just walk away. Volis ability to speed up throw over the shoulder, then slow them down, attack, and bite, is decent.
There needs to be some OP champions, and Ill agree voli is slightly OP (his damage against tanks is pathetic though, compared to garen), to help people who dont deserve to be in bronze to carry themselves out.
Im Gold and climbing, and my friend is diamond and climbing. We smurf and play games with bronzies, and it easy to carry some of those fools.
