ADCs are supposed to die when caught out and bursted

Are all currently ignoring these weaknesses that are supposed to be inherent. Vayne isn't as popular yet but I have played against it once so far and it was really just terrible.
The fact that Vayne and Kalista can build bortk plus a zeal item and crush your team while building
or
and just never die is honestly just cancerous.
Vayne and Kalista seem to be able to go
or
or
and the vayne I played against built
I feel like that last item would be even worse on Kalista due to her being a hurricane champ.
Graves and Quinn are building
and another item instead blowing people up without caring. Any suggestions on making these outliers more punishable? Also, can some Vayne players try out that vayne build some more I want to see if it can consistently destroy and by Vayne mains doing it more we can get a larger sample size.
