>A mathematical model showed that support is the least impactful role in the game (as in, having a good support or a bad support makes the smallest difference in winrates compared to any other role). Unsurprisingly, the same model showed that the most impactful role was JG, so having a really good JG was correlated with a huge WR increase, but a really bad JG with a huge WR decrease.
>Data showed that having an autofilled or first-timer support had the lowest impact on the game when compared to having autofilled any other role.
>ADC players flipped out because it implied that having a bad support is not the reason a lot of people here are hardstuck, some critiques where made in the comments about things that the model failed to account for. Most importantly, it was argued that the way "good" was measured indicated how good the player was at a champion, not at the role. And since supports usually can't carry the data was skewed.
>The model was updated to account for general player performance regardless of champion, and the model showed virtually the same results, but with ADCs gaining some impact because a lot of ADC champs are similar to each other. Support champ pick is more important, but even accounting for that its still the lowest impact role.
>ADC players goes on and on about how supports are boosted because their job is to let themselves be carried. And most high ELO players will agree that having autofilled support is better than autofilled anything else, because it's hard for a supp to carry and good ADCs can play around bad supports.
>Bad ADCs love to say they can't climb because their supps are bad, even though data and common sense agree that it doesn't really matter (or rather, it matters less than with every other role, including ADC).
TL;DR : Support needs buffs, and if an ADC player is hard stuck it's their problem and never the Supports. Support players are innocent.
