I think ADC is the hardest becuase mostly you really depend on your support to pull them moves. An ADC without a good support is helpless in lane. teh coordination is important and this is mostly impossible in solo queue.

Also mid is kinda difficult, becuase you ahve to balance farming and harrassing and ganks can be deadly if you just went all in (also you need to have 2 wards at least to be safe)
