ADC not actually carry

So, I've noticed this season there is an obnoxious fault in team comp play regarding ADCs. Regardless of whether you are a fed 7-2 adc within the first 8 minutes of the game or a 2-7 adc just trying to farm, you still need to rely on literally the entire rest of the team to win the game. The only valuable laning positions imo are top and mid. BOT lane is just there for either feed or help not lose the game by not feeding the other lanes/jg when they roam. Yes in team fights adcs can help beat down champs, unless they are all back line champs, making it impossible for every adc in the game to live within the first 4 seconds of the team fight. You are a meat stick for the jungle/mid, or you own the other adc and die in every team fight anyways. There isn't anymore substance to an adc than that because of how versatile they are making every other champion. Focus has been so much on every other aspect of the game that adcs have an extremely hard time keeping up. I've even seen it in LCS. ADCs don't really make the plays anymore. It will be a top laner or jungle with the occasional mid-lane carry.
