They are nerfing her vs squishies (removing crit from her Q is a huge hit to her burst) and buffing her vs tanks.
Right now we are in a tank meta and even then vayne isnt seeing a lot of play because shes just bad, even on the meta shes supposed to be good (and she cant lane vs most adcs anyway).
Surprised it took them this look to give her something.
Critmaster Garen3 votesthe problem is that vaynes kit has absolutely 0 counterplay. its impossible to deal with her if youre playing the "wrong champions"
explain to me why assassins needed counterplay added so adc can deal with them and dont get blown up without a chance to fight back, but its ok for a marksman to exist thats impossible to deal with for brusiers.
her 3 hit mechanic is already a shit excuse for counterplay to her true damage. and theyre buffing her by making it even easier to trigger, and increase its value.
why do melee carries like 
need a complex counterplay mechanic that allows her opponents to outplay her by denying her hits on her vitals, but vayne just gets it tacked onto her auto attacks?
why arent ranged carries held to the same standarts as melee carries?

She already has counterplay, her early game is shit, shes cant waveclear without items, she has no aoe at all on her kit or range extensions.
Shes not a very good adc in 5v5s because its just easy to cc and insantly kill her when she walks up to auto attack, ppl dont understand that the best you can do vs her is to straight up KILL her instead of building defensive items, she has a shitload of weaknesses on her kit for her only strenght on skirmishes 1v1 and tank killing.
Just compare this to someone like jhin, whos strorng early-mid-late, has cc, has huge range so he cannot effectively be zoned from a team fight, is much safer, compare most adcs kits downsides to vayne and you'll see why she needs something.
Critmaster Garen3 votesShe already has counterplay, her early game is shit,
thats not counterplay thats her powercurve. garen is shit early too and scales into late. nasus is shit early and scales into lategame.
but throughout the game they retain counterplay, while vayne doesnt.
shes cant waveclear without items, she has no aoe at all on her kit or range extensions.
which is a limit in the first couple of minutes until she grabs static shiv.
fiora cant waveclear for shit either until she gets a tiamat.
this is still not an excuse for the lack of counterplay.

shes a fucking monster in a 5v5 with the right support, and adc are not lacking in defensive and anti burst itemization.
"cc her and blow her up" is not a champion specific counterplay mechanic. it doesnt even work anymore with the current set of items in the game.
you cant blow her up when she gets shielded by her support for 3 times her health bar, on top of running g.a. and standing in redemption active.
shes also one of the most slippery champions in the game with her stealth mechanic and mobility. shes loaded with tools to outplay her opponents, while she doesnt have weaknesses that you can play aroubnd yourself.
and finally, her range is not shorter than that of other adc. no, she doesnt have abilities like sivirs boomerang, but every adc has to get into 550 range when he wants to carry. ashe isnt going to carry a teamfight by ulting and spamming her w. she has to walk just as close as vayne if she wants to auto attack.
vayne is nothing but a ball of stats.

Supports being broken/having broken items so vayne has no counterplay.
HMMM nice argument.

no, vaynes kit has no counterplay.
thats my argument. dont twist my words around. "cc her and blow her up" was your answer. and that shit is still not counterplay, even if it would work in the current meta.
counterplay mechanics are 
q that telegraph his movement and allows you to zone him off his axes to deny him a major portion of his damage.
counterplay mechanics are vitals that allows you to outplay her by protecting them inside walls to deny her the true damage.
shield that you can destroy by stepping on it.
health blobs that can you deny by stepping on them.
vaynes entire kit is nothing but a ball of passive and active attack steroids and mobility tools that you cant play around.
fuffychan2 votesDont bother arguing with that idiot about Vayne. He thinks she can 1v5 in melee range by standing still and auto attacking, he thinks ranged auto attacks should cost mana or gold or something, basically a whole bunch of nonsense simply because he cant learn to play.
Warlord Rhinark3 votesHer W and R itself is proof that she was never meant to be a burst champ at all. It doesn't matter her Q no longer crits. It doesn't make the other changes balanced. And even with her Q no longer being able to crit, she can still burst you down anyway so her Q no longer being able to crit does almost nothing.
