ALSO the difference between a good AD and a great AD is those who capitalize on an advantage early game.

Well then now your argument is focused not about the laning phase, but about trading damage, which I can see, but picture this. If your claim were to be about farming during the laning phase, you go ahead and farm as vayne. Sivir farms as well and we're avoiding trading damage for now, but then one of you guys starts to become aggressive. Now fighting against sivir, you would know that in your situation, if you were to be the first to be aggressive, you would lose at trading damage for she can boomerang you at a close distance with a less percentage of a chance for you to dodge that. But, if sivir was to engage first in that situation, your role in that fight is to avoid as much damage as possible. Thus you use your tumble at the moment in which you can guess when she's going to throw her boomerang, or if you have fast reaction, do it right when she has the throwing animation. Either way, there are ways to avoid her boomerang if you play smartly. Obviously that is why her Sivir's Q is considered a 'skillshot.' I'm not arguing that Vayne > Sivir, I'm just saying that you can't really compare the two in a one sided situation that Sivir will most likely win during the laning phase (= farming phase). It all depends on the player. Sivir can produce the higher output of damage, but that is if you let her to do that much on you and back to what you've just said, it all depends on the "level" of the player. There are those who know how to play against her.

I can accurately judge the usefulness of a champion in a game.

There is no absolute omg "best" ranged ad in the game that auto wins the lane or is the best pick for every team.

I like Corkis for example. High mobility, huge AoE burst damage, easy to push with R. A lot more harass and dps output than Sivir assuming both lands all of their skill shots (which Corki's is a lot easier to hit with)

Sivir is fine if your team is already ahead / winning the game, but she isn't the type of champion from what i've seen to be able to turn around entire games.

nooo. i just picked up sivir and i was gonna use her to climb to gold, but apparently everyone knows she's op D:

We don't balance the game around solo queue. Our high-level balance goal is around tournament play, which is an area where Classick, Roku, and I have quite a bit of experience. In turn, I'd like to ask you for your tournament credentials, sir.

We'll be watching IEM Kiev very closely. I believe the tournament will be played on the Ahri/Viktor patch, so it will be before any of these buffs and nerfs from this update. I trust we'll react accordingly. Personally, I expect Sivir nerfs in general. I feel she's a "top 3" ranged AD. However, I think people on the forums and solo queue are just underrating a lot of the other choices.

No need to create scenarios. Everyone knows that skillshot oriented champions will have higher damage output than non skillshot champions if they make those skillshots. Good players will make those skillshots.

And Good players know how to dodge those skillshots. Your argument is flawed.

**** I could feel the heat from here from that burn.

**** Mang you just got owned +1

Oh SNAP!

So Phreak, why nerf Vayne and as hard as you did?

Why not try out one, maybe two of the nerfs?
