Vayne has the highest attack speed growth of any ADC
Vayne's attack speed growth is 4% per level, matching Caitlyn's. I understand that it's because she doesn't have an attack speed buff in her kit like Caitlyn, but she does have an auto-attack reset on a 2 second cooldown.
Vayne is an abomination of a champion because she is really never weak in any stage of the game, and yet is a powerhouse late-game who can literally 1v5 if she's fed enough.
Has Riot not mentioned before that they don't like champions who never have a vulnerable period? I'm pretty sure they have. So why does Vayne get to be powerful at all stages of the game?
Something as simple as removing the base numbers on w's proc would make her easier to lane against.
As it stands her W, Silver Bolts, deals: 20/30/40/50/60 + 4/5/6/7/8% of the enemy's max health.
Let's say she's auto'd an enemy Sona with 1,000 hp 3 times. Along with the basic attack's damage, her w would also deal an extra 140 true damage.
Also remember that this is a passive, and therefore does not have a cooldown, meaning Vayne can keep procing her W over and over and over. Having this ability and her Q, Tumble (which also gives her bonus damage on her next attack for some reason), all she really needs to build is attack speed, if anything. This ability has no counter, nothing you can build against it, absolutely nothing to negate or diminish the damage.
She doesn't need to build much attack damage either because her medium-cooldown ultimate gives her 30/50/70 bonus attack damage, while her Tumble gives her bonus damage on her next attack scaling from max attack damage.
NERF THE NIGHT HUNTER
will help significantly against this, while it won't make Silver Bolts do less damage (the ability is made to be impossible to reduce, would sort of kill the point), it will make it take longer for her to proc it.
+ runes & masteries. 15% is nothing. Combined with crits, bork damage, W passive and straight up peel a good vayne is mission impossible to stop.
to be more effective. Even though it can't reduce Vayne's attack speed, nor it can reflect the damage done by her Silver Bolts, it is still effective against the normal damage done by her auto-attacks, and since she will have a lot of attack speed, she will receive a lot more damage from this item, in addition to it countering the small amount of lifesteal that BotRK has.

is the same you know.... ( unless you're gonna use your ult for poke)
