PSA: ADCs are worthless without peel
Nearly all assassins, divers and skirmishers have more mobility and gap closers than an ADC has escapes. This provides reasonable counterplay because if the ADC had more mobility than these champions then the ADC could endlessly kite them with superior range. Since an ADC will NOT have more mobility than champions like assassins who can easily kill an ADC 1v1 it is vitally important that the rest of the team provide some form of crowd control to stop the assassin/diver/skirmisher from popping the ADC within the first few seconds of a team fight. ADCs do have the highest damage potential in the game but that damage is sustained DPS, not burst damage. ADCs are worthless if they can't consistently auto attack. If all your ADC is doing is burning everything he can to get away from an assassin/diver/skirmisher then he is not putting out DPS which means that your team will most likely lose the team fight if the other ADC is able to auto attack freely.
I know it seems simple and very obvious but after dozens of game of my entire team charging in while the fed mid/top/jungle 1v1s me it starts to get very, very frustrating. Its not an issue of your ADC not being able to kite, its simply differences in champion kits and playstyles which stack the deck against your ADC. Even if your ADC burns their dash, their QSS, their heal, and their flash chances are they still won't be able to escape the assasin/diver/skirmisher without help. And even if they do manage to survive they will be completely taken out of the fight, resulting in a 4v5 that your team will most likely lose.
So the next time you are in a team fight don't tunnel vision on the squishy carry on the enemy team, especially if there is a fed assassin/diver/skirmisher on the enemy team. Keep you eyes open and engage the assassin/diver/skirmisher if he dives your ADC, especially if your ADC is the most fed member on your team.
NOTE: By ADC I mean the squishy marksman that goes bot lane, not some freak of nature like bruiser Graves top lane.
can kite most melees without limit if they play it properly. then there is
who can just facetank his enemies, and
with running passive. forget ever catching her with her mines, and 70% slow on her w when her ghost is active. and its not like its hard to trigger. she just needs some random assist in a teamfight off the splash dmage on her rockets and she starts flying.
