ADC? It seems that you like to play ranged ADCs, so I suggest you try people like Kog Maw, Ezreal or Greaves etc etc, each of them have their pros and cons. I personally find Kog Maw fun because you can snipe people with your ult ^.^ Ezreal is also fun too but all his Skills are skillshots and require skill to use.
Other than the "Typical" ADC you encounter in the game, you could also try other people like AD LeBlanc, She has one of the best kit for an ADC ( Snare, Silence, Gap Closer, and even better, her ult clones her previous ability!) Although her abilities don't scale at all with AD, shes still fun to play as, and it certainly screws with the minds of your opponents as they weren't expecting the unexpected ^.^
All and all its pretty much up to you to experiment with the champs you like, as everyone hass their own style and liking, but it shouldn't mean you should be restricted to some specific champs
Good Luck
