Hello, Jax Mains investigator, we have analyzed different dps stats and we have seen different things and i came down with this tier list of keystones
1.--Press The Attack (PTA): Best of keystones on Jax it deals a good sustained damage while keeping up, keystone that you should probably go always
2.-- Grasp of the Undying: It offers a different tank jax when a titanic and Sterak will have a lot of synergy and offer you a different kind of duels
3.-- Lethal tempo:Unless you are smurfing jax and you are constant challenger you will not be using this, as this is kind of risky because the enemy can just go aways after they see the proc of Lethal Tempo.
I have a excel archive with some builds and dps tests on these new keystones.
Hope you have fun with our champ because on the Jax Mains discord we see a bright future.
PS to everyone that says guinsoo memes: Dont build Guinsoo on rankeds unless smurfing please its an unreliable item that takes too much gold and unless your enemy is not that smart it will not be good.
