First, I was looking forward to Vi, but playing against her I notice that she is way too powerful. Vi can tank and almost solo an entire team and barely any champion can go face to face with her. Maybe consider nerfing her a bit?

I noticed as well that most people that play Vi can solo anyone, even if they have armor and health she can still kill them. Shes bit op, maybe a bit of a nerf would be good.

Do you play her in the jungle or top? Because in top, I consistantly abuse Vi's lack of range or poke and bully her into submission. Then when she dives into my team we massacre her and go on.

But in the jungle, she's pretty much a boss.

try Mundo, beat her twice

I think her biggest issue is her mobility. Unless you stunlock her, she can pretty much maneuver in and out of a fight at will.

While I get that this is part of her concept, fact of the matter is she just scales too well as a tanky-DPS/Triforce. Lowered ratios and base values, such as how Talon's mechanics are working would probably put her in a better place while still keeping her maneuverability as it is.

Otherwise, her mobility and gap closes/openers needs to be decreased. A tanky-DPS shouldn't be playing like an assassin as a 1v1-monster-against-squishies (and as it stands, entire teams due to her scaling).

Vi is a fighter champ, this is what they do. She isn't OP, there's just a piece of the big picture missing from your line of sight

Dominated her a few times. Once with Gangplank, Xin and Volibear. She's not that OP. Don't get me wrong, I have gotten face punched a few times from her as well. So it's even.

OP - she must have been Fed, and like most fed champs they roll hard.

Vi is def not OP if anything she is UP or balanced at best, cc screws her, she has no sticking power, no sustain and generally has a hard time dealing with many of the standard top champs.
