I don't main adc so feel free not to take my view to heart:
Since you can't control what your team picks (you won't always have a janna or gragas or azir like the other guy pointed out), you'll have to rely mostly on yourself. For this reason, champions like Lucian and Kalista (due to great mobility) or Cait (can sort of move in and out with that great range) seem to be popular in solo queue (mostly mobile champs). I'd suggest playing a mobile adc to help here (if you're blind pick at the time, probably lucian) and trying to keep track of spells used as best you can.
If Pantheon stuns someone else, you can attack a little: if wukong e'd someone else, can attack a little. Just need to know when to backup, if you're even a little too forward a good player will punish that.
Hopefully whatever you decide to try works out, good luck!
