Actually, Jinx is not considered a hyper carry statistically speaking like Vayne or Kog'Maw. Someone actually pulled out the graphs and numbers to educate me on ti when I called her a hyper carry.
Apparently, current Jinx is an early and mid game beast with a super big spike during the teamfight stages. But once you hit the 40 and 50 minute mark her success-rate drops off significantly whereas Vayne and Kog still shred anything in front of them. I am not sure if this has always been the case or if she has always statistically been like this, but that was the official stats from Riot themself they linked me.
Now, I can understand this being that she has no escapes and is rarely protected the same way Kog is once those big late game teamfights hit. I still think she is very strong in this meta looking at those stats since this is a much quicker gametime meta than previous so it fits her power curve. I'd still play her if I was back in the adc seat. Currently playing support since I never trusted my supports when I was adc and they never dropped vision reliably. Now, I manage the vision.
