Jax is outclassed by Riven in every possible way atm
She has a way better laning phase, she can roam better, she is more mobile, her mid game is way better, and she carries games as hard
Anything going to be done about this? He's been a troll pick in any decent elo since last May when he got his base stats nerfed to be lower than ranged AD's. Yes, He has less base armor than most ADCs, including Ashe.
The only two top lane champs worse than Jax atm are Gangplank and Olaf
