And botlane's performance is heavily dictated by who shows up to the lane. If you are a jungler or mid player who never roams bot, you are doing something wrong. You can't be mad when the enemy mid roams bot, gets a kill/double kill, takes turret, frees up support to make plays, and frees up ADC to help push turrets; what they are good at, and possibly getting dragon. At that point, you have something like an 80% chance to win the game. You can't sit in lane and cry because you didnt take advantage of that and the enemy mid/jg did.
The meta hasn't been sit in lane and farm up for a long time; even when ADCs were weak. The meta has been go 3-5 bot, dive/gank/take turret/take drag, rotate top/mid for a long time, even when ADCs were a meme. Why people still can't grasp this, even after tuning into LCS and seeing it on a game by game basis, blows my mind. Even in low elo games the 4 man bot strat is alive and well and wins most games. Even if ADCs were nerfed into the dirt like everyone wants, this is still going to be the meta, and you are still going to have a 3/0 ADC showing up mid/top taking your turret after drag because you refuse to acknowledge it while your enemy counterparts do.
