As an adc main, sometimes I have no choice.

As my whole team attempted to dive their carry, I was being chased by chogath, and they did nothing to peel him off of me. As a result I had to keep kiting him for miles, to which my team all died because they couldn't reach their carry and responded by asking the enemy team to report me for being a "noob adc who focuses the tank"-_-

You have to keep in mind, both teams have the mindset that they need to focus the carry. If you keep your carry at a safe distance, they can't focus them and you can take down the enemies 1 by 1. If their carry goes in the middle of your team to try and focus your carry you can just nuke their carry down easily.
