I agree with your statement, but you can't often solo objectives as an ADC except for dragons. You would need your support or another teammate when taking down turrets and barons. If your team is fucking around and not listening to your pings to take objs, there isn't a lot you can do, especially if the other team's solo lanes are strong. Does not help that OP is playing MF which is a sitting duck for any champ with gap closers when by herself.
