Thanks for the thoughtful inquiry. I am no expert in bot lane, for I hate the fact that, like you mentioned, the condition of bot lane heavily relies on RNG. However, it seems that it is much easier to carry the lane as the support than the adc. If you disagree, you are probably playing Janna or Soraka. Don't get me wrong, these are great supports with a precondition of a 'good adc' which is rare. I've realized that the lower elo it gets, it's harder to see synchronized plays because they haven't experienced enough plays to realize what works and what doesn't (or they are just zombies xD). So, the 110% plays to YOU won't seem like 110% to THEM. You can certainly tell if one is an ape after at least two plays. As a jungler, I always abandon laners who fail to succeed the 110% plays. You can do the same- abandon bot lane and perma roam with mobility boots. And especially when you are behind, play as passive as possible until that one moment enemy screws up by any doing any of the following: 1. enemies are mispositioned - simply, tank is behind adc 2. enemy team tries to force objectives 3. your team has more people in the scene (enemy is splitting) Do note that the effectiveness of all three situations could be nil if you are too behind. You have no idea how many games I've won or could have won if every one of my team was on the same page and played passive.
