Jax needs to be rework on passive due to new runepage

uh, do you have any proof for this?

proof?

Rageblade it is a bad item, and even then lethal tempo requires to be completely sticky to your opponent also rageblade needs to stack 6 hits to have that attack speed

Except he won't survive the time needed to stack rageblade and the lethal tempo, or gets cc'd until it goes on cd. I tried lethal tempo on an ADC, it's a noob trap. More often than not you actually have to hit and run, starting the lethal tempo and running away while it's active. It only works in the Kog + his 4 bitches comps where Kog can stand there and shoot you at 5.0 AS without bothering to kite. Any other ADC will waste off the duration of the steroid when trying to kite in teamfights, it's only strong in 1v1's.

Overcapping your attack speed just for lethal tempo procs is a terrible build. Even before ignoring that full damage Jax is almost completely useless, it's simply going to be less damage than a balanced build that focuses as much on getting big hits as it does on getting a lot of hits.
