My opinion about Jax from a Jax main.

Jax is the first champ I ever bought. most played champ and highest win rate. now with the itemizatiom. a lot of the people have been picking him up. and prob due to the meta too. but man. when i face a jax. and hes 0/3- 0/5 early game and hes not good at all. and then late game he wins the game for the other team. man i can say Jax with rageblade is the best jungle carry in the game. hands down. honestly i focus jax but its really hard to kill him even though am familiar with him . and he does a a shit ton of damage. its just unbelievable how strong he is now.

i think he trumps tahm kench. yasuo in terms of helping the team winning a game. he can melt turrets and melt anyone. I mean late game even jax hard counters. can't stop him.
