Throughout all of Worlds, Jax has not been picked at all and has been banned in one game.
Between play-in groups, play-in knock-out stage, and now as of day 2 groups being complete, Jax has not been picked once; he was banned in one game during play-in groups. That is well over 50 games between the best teams in the world with different metas, regions and play-styles being largely blended in. If Jax was this dominant, overpowered, no counterplay/no weakness having champion, you would at least see him in competitive play at the highest level. We have a decently large enough sample size at this point.
You want to know what has been played a bunch? Orn, Sion, Shen, Poppy, Gangplank, Cho’Gath and Maokai - all of which are abusing grasp. Of the Conqeuerer champions, only Camille, Aatrox, and Irelia have been played consistently. Again, if Conquerer was so overpowered (and at one point it was; that is no longer the case), you would absolutely see it being used/abused more. In the interest of full disclosure, there have been other champions played consistently that do not use conquerer and were champions not mentioned: Urgot, Ryze and Gragas, none of which used those keystones (urgot has used grasp in a few games tho).
I absolutely acknowledge that champions can be busted in solo queue and low-elo (see Tryndamere, Riven and Nasus), but is Jax really broken? It’s time to start being honest with yourselves, Gameplay-folks. Maybe Jax isn’t the problem, maybe it’s you. I’m not going to bother referencing Jax’s statistics because looking at a champions statistics in isolation without standardizing performances of all top laners, including Jax, and comparing their performances with each other is the only way statistics are going to give us real definitive answers. And quite frankly, that’s work I do not feel like doing and even then, of all the sites out there, their information isn’t going to be as accurate as Riots information; so even if I did do it, it probably wouldn’t be accurate. And I can promise you riot is running these statistical analyses every day. If they haven’t nerfed Jax or conquerer yet, chances are they don’t see any outlier performances with them. And if these things aren’t popping up in the final tournament amongst the best teams in the world with over 50 games played, between these two things, it’s probably most likely that there’s nothing wrong with them.
I now welcome my downvote bath.
