Jax is in a weak spot.
It's something I've noticed for awhile now and didn't have to much assessment on until the past few weeks. Jax has always been someone who is a ton of fun to watch(also play) and hard to deal with starting around late mid game. Lately though it pains me to see him. With a lot of passive things and what the meta favors it's no wonder how he's in a bad spot, he's lucky if he can even make it to the late game unscathed. We can only be hopeful that the near future changes to the jungle will help put him in a better place.
Though Just watching his dueling I can say he may need some very minor buffs (BUFFING
???!!! Go ahead and Down Vote)
In his late game he is suppose to be a God Tier duelist along with a few
other champions. Though Jax is a decent pick into Camille right now but even her, someone who brings far more overall utility to the team than Jax , can out duel him if played with little effort and ult timing. If Jax is not doing good as a late game duelist then something is wrong.
So a viable buff suggestion could be buffing his ult passive to where the _ more consecutive strikes _ Jax lands on an opponent shred mr to help him do better in sustained fights making him have better late game dueling potential and making a better trade off for his shit early game. Either that or let him use real weapons because honestly, that lamp post isn't doing shit for him right now.
