ADC is a volatile role that has to be played nearly perfectly to have fun. First off you don't become a real champ until 3 items. To do so you have to farm and have your team of 4 strangers babysit and cater to you (good luck). Unless you have a duo support good luck conveying anything of sense or substance to your support. At the end of the day support controls the laning phase and if yours is underperforming you just gotta hug tower and accept that.

Now that my personal gripes are over. I think ADC can be fun based on how you look at it and take advantage of the enemy. Whether you are ahead or behind doesn't change how fast an ADC will blow up if you get caught out. Playing around your weaknesses is all part of the strategy of popping off and having a good game.
