ADC are too vulnerable this season so far

as of season 7's start, ADC players have had a rough time dealing with the new assassin mid meta where all of them have some way to dodge cc and get to a back line and out safely while one-shotting a carry. My idea is that we either buff adc so they have an ad/armor item like how mages have zhonyas, or we nerf the main assassins wrecking havoc like fizz, leblanc and rengar. Individually they have weakness in lane, but their roams are too strong for even braum to block. I understand this is the reason for them being assassins, but please riot, nerf those who need them, leblanc presses q then w with her passive and one shots a carry while fizz jumps over walls and cc to one shot a carry with a single urchin strike. We carry players know you have good intentions with making the game more champion diverse, but please, we adc have only 3 choices per 4 months to play and it gets ridiculous when we cant even play our role because we are afraid of assassins roleplaying garen and sitting in a bush waiting for our booties. my main point here is that adc need buffing and assassins need slight nerfs to base damage or scaling.
