ADC Meta
The three main ADC's played are Tristana, jinx, and Lucian, with Corki gaining popularity. Vayne is also getting popular too, I don't know why people pick as much though, because she does scale strong into the late game.
But what I'm trying to say is for the other ADC's, are the ones that are "outclassed" like Varus, Sivir, and Ashe. Some good balanced ones are Graves and MF, but I see MF being a stronger choice because of her attack speed steroid, grievous wounds, and magic damage on hit. And of course Caitlyn is a good choice too, but she kinda falls off late game, mostly being a lane bully. Then there is Koggy, couple of months ago, he was considered a hyper carry, which is true now, but he takes EVEN longer to scale up because of his poor mobility and base 500 range.
But the top tier ones, have two of the following: Gap closers and steroids (attack speed). Sure other ADC's have these, but they aren't quite as strong as a double hit passive, dash, and movement speed boost (Lucian) or a big ass jump and 110% attack speed buff (Tristana). Nerfs do need to happen, imo Jinx needs one, but buffing the deemed "outclassed" ones need to happen as well. Like buffing Ashe's useless passive, because it takes a while to build up, and you're an ADC ffs, you're constantly in combat so it can't build up.
I am not saying that every ADC is terrible, because you can climb elo with any of them, but they are always outclassed.
Oh and nerf Nami.
