adc or assasin

So season 7 is coming soon and my friends said the game would be completely different and fix some annoying features. My favorite role is of course shyvanna jungle and caitlyn adc since ashe is pretty team reliant.

I've played about 10-15 games and noticed something, I get this is the season of the assasins and they're really strong, with some cc from my support he can lock them down and we can take them out. But no human reaction speed stops a talon from getting a free kill for basically clicking on me, I'm caitlyn so I know I have some kite potential, so I stand on a trap and have my E ready but he just taps, while snares preforms a 1100 damage combo at level 8 and gets a free kill, then proceeds to walk up and kill basically anyone he wants. This is annoying but I guess it's intentional that adcs are squishy and require peel, but even with the sweepers we know he's walking up to me and doing a teleport 1 shot, we only kill assasins by predicting them, and I understand map awareness to avoid them, but during group fights I can be backline with a nautalis and leesin sitting there and go from 100-0 in 1 second.

Apparently there are no defensive items for an adc to prevent instant death, I've just taken to buying hourglass frozen mallet black cleaver IE and whatever boots so I'm tanky with at least 1 survival item. but meanwhile vayne can turn on anyone since she has an ability to keep her safe as an adc. Maybe not have a class click to instakill, but the tank meta is still around so 4 tanks counter 3 assasins.
